Colonial history of the United States

The colonial history of the United States covers the history of European settlements from the start of colonization of America until their incorporation into the United States. In the late 16th century, England, France, Spain and the Netherlands launched major colonization programs in eastern North America. [l] Small early attempts† such as the English Lost Colony of Roanoke†often disappeared; everywhere the death rate of the first arrivals was very high. Nevertheless successful colonies were established.European settlers came from a variety of social and religious groups. No aristocrats settled permanently, but a number of adventurers, soldiers, farmers, and tradesmen arrived. Diversity was an American characteristic as the Dutch of New Netherland, the Swedes and Finns of New Sweden, the English Quakers of Pennsylvania, the English Puritans of New England, the English settlers of Jamestown, and the â€Å"worthy poor† of Georgia, came to the new continent and built colonies with distinctive social, religious, political and economic styles.Occasionally one colony took control of another (during wars between their European parents). Only in Nova Scotia (now part of Canada) did the conquerors expel the previous colonists. Instead they all lived side by side in peace. There were no major civil wars among the 13 colonies, and the two chief armed rebellions (in Virginia in 1676 and in New York in 1689-91) were short-lived failures. Wars between the French and the British†the French and Indian Wars and Father Rale's War†were recurrent, and involved French support forWabanaki Confederacy attacks on the frontiers. By 1760 France was defeated and the British seized its colonies. The four distinct regions were: New England, the Middle Colonies, the Chesapeake Bay Colonies (Upper South) and the Lower South. Some historians add a fifth region, the Frontier, which was never separately organized. [l] By the time European settlers arrived around 1600-1650, the majority of the Native Americans living in the eastern United States had been decimated by new diseases, introduced to them decades before by explorers and sailors.

Mass Media and Younger Generation

Abstract Entertainment has a significant influence on the people. The effects of entertainment can both be positive and negative. This influence of the entertainment industry has grown tremendously over the years. The influence can be greatly attributed to the advancement of technology. Entertainment is mostly through the media which includes; the television, magazines, newspapers, radio, and internet, among others. The influence of entertainment on the younger generation affects the way that they dress, talk, and act. This is because the current generation and society depends on entertainment as a form of communication and information.The society, therefore, turns to entertainment for the daily activities like education, health care, traveling, work, and personal relationships. This paper is going to look at the effects of entertainment on the younger generation. In addition, it is going to look at how entertainment affects the young generation in terms of their acts, the way they d ress, and talk. Introduction A nation like America is an example, of a country that has developed in terms of entertainment (Fisher 58). It is one of the countries that has got and has produced some of the greatest entertainers.The country is one of the leading producers of entertainment in the planet. In addition, it is one of the nations that there is a greater influence of entertainment on the younger generation. The effects of entertainment on the younger generation in America can be said to be both positive and negative. The influence is mostly on entertainment media such as television, radio, and the internet. The influence on the upcoming generation has affected their expression and vies on the culture of America. The influence is on how they talk, dress, and act on the society.This has been caused by the social media pressure that is sweeping through the country. These are the influences that entertainment has on the younger generation in the country. Entertainment The citiz ens of America depend on communication and information for their daily activities. These activities include; work, education, entertainment, traveling, personal relationships, and health care (Kearney and Crandall 89). The people use the newspapers or television to get news. They make phone calls, browse over the internet where possible to make decisions that re based on the information that they need and get. The decisions should be made depending on the values and beliefs that exist in the society. The younger generation, therefore, need to have facts and use experience when making certain decisions. The media are the place where most people get the latest and current facts and news on significant issues. Most of the younger generation, therefore, turns to the media which is a form of entertainment to get news and education. This in effect, has influence on the younger generation.The upcoming generation, gets influenced by the mass media and this in turn affects the way that they conduct themselves in the society. The influence works in several ways and can be caused also because of several reasons. This can be either positively, negatively, or even both. How the influence works The television is the common and most known form of entertainment that has got influence. The television exposes the upcoming generation to thousand of images. These images include; celebrities advertisement, violence, sex, among many others. The exposure to the younger generation is too high when considered in terms of years (Scott 9).The media should be responsible for the programs they air. They are the ones who should help in shaping the beliefs, values, and decisions that the upcoming generation makes. The companies that own the media are the ones who are in charge of entertainment movies, radio and television broadcasts. Moreover, they are the ones who authorize the programs, sports, and video entertainments. In addition, most of the companies that offer these services are also integrated in the wireless phones, telecommunications, music industry, electronic media, video game software, and more.Therefore, the companies should consider programs that nature cultural values and beliefs that do not have a negative influence on the upcoming generation. However, some companies have merged to shape the beliefs and opinions of the users. It is significant to consider what the younger generation is exposed to daily through the entertainment avenues. This calls for the other people in the society to be vigilant in protecting the values and beliefs of the country. They should look at the entertainment that is given from, different perspectives; as opposed to ho the media gives it.The advertisement done by the media is another exposure to the upcoming generation. Although, the media makes a lot of money from the advertisements, they have some negative influences to the younger generation. Many citizens are influenced, by the advertisements, and this makes them buy th e things that they are told that are good. Decisions are made from the advertisements that the citizens are exposed to daily. This is based on what is seen on the newspapers, magazines, or television. The product is deemed to be the best and most people make decisions based on what the media is propagation.This creates influence as people tend to trust the media. The same applies to the younger generation that is exposed to this form of entertainment. The effect and influence on the upcoming generation makes them buy what they watch over the televisions. This is mostly influenced by what they consider being their celebrities’ favorites. The upcoming generation will buy what favorite celebrity has advertised and what they deem to be acceptable in the society. This is based on the fashion that the media has created and imposed on the minds. The influences can be at times positive or negative.A positive example can be a sport that is getting media attention. Many of the younger generation will want to be identified with that sport. The popularity in the society and among the friends for the sport can make a youth be identified with the sport. This will make the upcoming generation start practicing for the sport with the idea that it is cool. The influence will turn out to be positive as the youth will become healthier from the exercise and have fun with friends. An example of a negative influence for the younger generation can be the use of cigars. This can be as a result of seeing a celebrity movie star using a cigar.In addition, the exposure to images with excessive violence, junk foods, and sex can influence the upcoming generations negatively. The upcoming generation is in a stage of life that needs some acceptance from the peers. They would like to feel loved and be successful in whatever they venture and try (White and Andsager 72). Therefore, the creation of the media of ideal images of beautiful women and handsome men as the real characteristics of successful people through television and movie influences the younger generation. This will make the upcoming generation want to look as the celebrity.They will copy the dressing styles so as to feel cool and successful like the images of the celebrities. The youth are, hence exposed to buying dresses and stuff that can make them look like the celebrities who are considered to be cool and successful. The influence of the entertainment industry has had an effect on the youth’s obesity and anorexia nature. Many upcoming generations in the country are fighting obesity. This is happening, while, they are exposed to most advertisements that carry junk food advertisements. The advertisements are there, yet, they give ideal images of successful people as wealthy and thin.The women are the ones who are mostly affected with this type of influence. They are so obsessed with loosing even in cases which they are not declared as obese. Many women are thin in the society as they want to r esemble and look like the thin celebrities, and super models that they see in the images, in the entertainment industry. The women, are, therefore, engaged in disorder eating habits that mostly lead to severe issues of health and in worse cases even death. Effects of violence in media Watching a movie or television exposes the upcoming generation to images of many people hurting others and violence.This type of exposure can have some influence on the upcoming generation. A person can easily become disturbed because of such exposure. This normally happens to the children who are exposed to this type of entertainment more and more each passing day. As the children grow, they begin shaping their personalities. This includes both beliefs and values. A child who is exposed to this form of entertainment can become very aggressive. In addition, these children can lose their sense of fiction and reality on what they are exposed in the movies and television.There are incidents and scenarios that have been reported of children carrying guns to school. Such kind of incidences where the children also hurt others can be attributed to the influence of the entertainment. This affects the cultural values and beliefs of such children. The behaviors of this type are associated with children who are mostly exposed to the excessive use of war images and violent video games (Coleman 112). The media using real war as a form of entertainment also exposes the upcoming generation to negative influences. The children need to be educated and informed, on the good forms of entertainment, to be watched.In addition, they need to be informed that the video games do not have winners or losers just as in the real war. Entertainment impact on society and the upcoming generation is significant. In addition, the influence of entertainment on public opinion cannot be ignored. The entertainment forms can change the public opinion of the upcoming generation in different ways. This depends on the ob jective of the form of entertainment. Television as one of the greatest discoveries of all times has so much influence on the upcoming generation. Television can be used for many purposes. This depends on the choice of the individual that uses the device.This can be used for entertainment purposes, like; watching music or soap. The shows that they youths are exposed to when watching television have created so many controversies. This is because of the influence that they have on the younger generations (Petley and Barker 34). The television has both advantageous and adverse effects on the youth. This will depend on what the viewer sees. This explains why the entertainment shows that are aired are full of controversies. Most of the shows are just on dates and celebrities. These types of shows are what influences the future generation that includes the children and youth.Most of the influences unfortunately are not positive. Studies indicate that there is a trend that is coming up whe re most shows are just for publicity purposes. This makes the youth find themselves easily influenced to be part of the shows to feel cool. The shows that help in increasing learning processes on the youth receive little publicity. These are the shows that can help the youth to nature good moral values and beliefs (Desilet 109). The television promotes entertainment and education. However, it is an individual’s responsibility to derive what he wants from the shows.Most young people are corrupted in the minds by the entertainment forms that they see. The youth fall prey to the many of the misleading advertisements in place. They get confused by asking on the celebrities that are being advertised. Furthermore, they get manipulated in their thinking. This makes them think of violence and criminal things. The more the youth is exposed to the entertainments the more they get influenced to the message that they get. Their social and cultural behavior is affected by the entertainmen t. The children are exposed to the negative influence of entertainment as parents are not there to control them.Some parents work till late and when they get home they are too tired to help the children in activities. They get glued to the television plus their children. Upcoming generation feels confident and they do what they feel like. In addition, visual effects normally lasts long on a person and this can leave some adverse effects to such an exposed victim. The advancement of technology has made things worse. Most of the television stations relay their programs through the satellite. This has left the parents with no control on the programs watched, and, therefore, the children remain exposed to indecent entertainment forms.The youth has also taken advantage of the same. They use the entertainment field to get knowledge and information from the television. Most of the young generation normally watches programs that are mostly entertaining. No wonder, television is considered a s a source of entertainment instead of a source of knowledge. This is the reason as to why television has to a great extent adversely affected the upcoming generation. Many youths have favorite celebrities that they look up to, as role models in their lives. This makes them to look for them in the movies or magazines. The reason behind this is to get the latest fashion trends or air styles.The youths look, on the magazines, to see what the celebrities have and the scope of the new trends that are considered hot. The entertainment industry is constantly changing perceptions of the youth. This changes the perception of who they are and what they think of themselves. In addition, the entertainment industry is what can be attributed to the changing trends in cultural ways. Most people look at the celebrities and entirely change their own ideals and views so as to mach what is considered to be perfection. The youth wants to be associated with money, ideal cars, and careers. The simple th ings in life are becoming less appreciated.This happens as people tend to look up for those with more wealth. They compare their lives with such people. The youth wants something bigger and something more. This is what makes entertainment have a constant impact on the societal trends. It is the aspects of the entertainment industry that makes the youth know how much they are rich and how famous they need to be in life. The constant advertisements, magazine covers, and other entertainment forms are what overwhelm the society. Moreover, the entertainment industry is what is responsible for most of the upcoming generations changing trends and perceptions on culture and the way of life.The shows that are aired make the youth look at their own lives. This makes them feel the need to do something different. Divorce is also becoming common in the society. The trend is mostly seen in celebrity couples. Cases of the celebs getting divorced are there every day. This has made it like a routine to those who are also in the media industry. The divorce cases are publicized in the media as something normal and good in the society. This has made the youth look at divorce as something that is insignificant. The society has also not carried any negativity on divorce of late. People run to marriages instead of dating.This whole situation has been created by the celebs. The celebrity couples have made divorce a trend. Moreover, the celebs have made the meaning of divorce be of less meaning and look like normal in the society. This trend has caused the youth to follow suit. The entertainment industry can be said to be the reason behind the change of perception and trend of divorce. The youth has been influenced, by the entertainment industry, to do cosmetic surgery. The trend has already swept through the society and is common with people who want to look like celebs or be more beautiful. There are shows in the television programs like DR. 20210 that have made plastic surgery be t he in thing (Durham 120). The shows make the youth want to look like the celebrities. They do this by trying to transform them to look like celebrities. They give them the different cosmetic and plastic surgery procedures that exist. The message passed is that a person in his own identity is not handsome and good. The trend encourages the youth to try plastic surgery in order to have perfect bodies. Therefore, the reason of not having a perfect look is not there as there is the option of cosmetic surgery. This has made the celebrities, to, also, have plastic surgeries to enhance their appearance.This is done with the belief that it will help in carriers, but, the youth just emulate the trend for the sake of it. The trend has made many youth to lack self fulfillment as they feel they are not good looking or good enough. Conclusion The entertainment industry has both positive and negative influence on the youth, but, it is not entirely bad. The negative effects and influences that the industry has, on the upcoming generation need, to be changed and recognized. This can help the youth so that their minds are not that clouded with the celebrity perfection ideas.The youth need to be educated and informed on the need for self confidence and self fulfillment as they are fundamental to true happiness in life. These traits are hard to attain for the youth because of entertainment and media industry. The industries are constantly showing and sending messages to viewers on the definition of perfection. This makes it hard for many of the youths to be contented and happy with their personalities and looks. The youth should stop to look for celebrities, movies, and television shows, for ideal and perfect life.The obsession created by the entertainment industry influences the youth’s way of life. They change the way they dress, walk, and even act. The entertainment industry will continue to have effects and influences on youth and societal trends. The influences shoul d be worked on, to make them have positive effects on society and society as a whole. This can involve the transformation of the celebrities, actors, and models in the entertainment industry. The effect can be huge and tremendous on the upcoming generation and society. The changing trends in societal beliefs and values can be influenced to be positive ones on the youth.Things can be better when the effects of the entertainment industry lean more towards the positive influences than the negative influences on the youth. This can be done knowing very well that America is one of the leading producers of entertainment and as such it is a significant component in influencing the behavior of the younger generation. The entertainment industry has influences on the upcoming generation views and expression of culture. This is depicted by the way that they talk, dress, and act on society through social media pressure in the country.You can get a custom research paper[->0] on this topic at Ess ayLib. com.

Preliminary Test and Solubility Classification of Organic Compounds

Preliminary Test and Solubility Classification of Organic Compound Keene Louise Topacio, Christopher Jay Robidillo Abstract The experiment focuses on how to classify organic compounds by its functional groups. It is done by preliminary test and with the solubility test. Preliminary test used two known compounds also the unknowns. Physical state, color, odor, and ignition test were noted. The known compounds are inorganic and organic compounds. A comparison is made from the observation in the unknown sample, by which we had concluded that there were two organic compounds and one inorganic among the unknowns. In order to have a strong background about the solubility test, we first classify organic compounds of known functional group using the said test. Butyl bromide, ethanol sucrose, butyraldehyde, ethanoic acid, methyl amine, nitrophenol, diethyl ether, benzoic acid and propanone were used. It is found out that they are class X, Sn, S, N, Sa, Sb, S, N, A1 and Sn, respectively. We use water, ether, HCl, NaOH, NaHCO3, H2SO4, litmus paper, and phenolphthalein in classifying each compound based on their solubility and color change. It follows a certain scheme on testing the compound. Each test will link to another test until we ended up with the class of that compound. We finally determine the class of the three unknowns. It is found out to be an Sb – amine -, S -salt -, and an N -aromatic compound-. Keywords: solubility, classification, organic compounds, solubility test, preliminary test Introduction One important part of experimental organic chemistry is to be able to analyze and identify an unknown organic compound from its functional groups. There are several steps in order to acquire this and there is no definite process. But there are systematic ways in different experimental organic chemistry books. For this experiment it will emphasize the preliminary examination and solubility characteristics of some known organic compounds and unknown samples. Preliminary test is basically noting informations with lesser effort compared to the other tests the physical state, color, odor, and its ignition properties. Physical state of a substance can make a distinction among organic compounds for the reason that at room temperature most of organic compounds are in its liquid state. This is due to the intermolecular forces of attraction in the compound. The color is also informative because most pure organic compounds are white or colorless. Some discolorations of brown color are effect of oxidation reaction. The odor of many organic compounds, especially the ones that have lower molar mass are highly distinctive. Also, functional groups have its' own different smell particularly alcohols, ketones, esters, aliphatic and aromatic hydrocarbons. Caution must be observed while smelling the unknown sample because large amounts of organic vapors should never be inhaled because of toxicity. The ignition test involves a procedure in which a drop or two of a liquid or about 50-100 mg of a solid is heated gently on a crucible with a bunsen burner flame. Whether a solid melts at low temperature or only upon heating more strongly is then noted. The flammability and the nature of any flame from the sample are also recorded. A yellow, sooty flame is indicative of an aromatic or a highly unsaturated aliphatic compound; a yellow but non-sooty flame is characteristic of aliphatic hydrocarbons. The oxygen content of a substance makes its flame more colorless or blue; high oxygen content lowers or prevents flammability, as does halogen content. The unmistakable and unpleasant odor of sulfur dioxide indicates the presence of sulfur in the compound. If a white, nonvolatile residue is left after ignition, a drop of water is added and the resulting aqueous solution is tested with litmus or pHydrion paper; a metallic salt is indicated if the solution is alkaline. Solubility of an organic compound in different solvents can present useful but not efficient information about the presence or absence of certain functional groups. It is because the basic principle in solubility is â€Å"like dissolves like†. In order to have a more distinct result a systematic approach can be considered and it is by solubility classification. First is to test the solubility of the unknown in water. Several structural features of the unknown can be deduced if it is water-soluble. It must be of low molar mass and will usually contain no more than four to five carbon atoms, unless it is polyfunctional. Also, it must contain a polar group that will form a hydrogen bond with water, such as the hydroxy group of an alcohol or a carboxylic acid, the amino functionality of an amine, or the carbonyl group of aldehydes or ketones. Esters, amides, and nitriles dissolve to a lesser extent, and acid. chlorides or anhydrides react with water rather than simply dissolving in it. Test in ether for water soluble compounds are also observed this is to identify further the functional groups in ther unknown. On the other hand, alkanes, alkenes, alkynes, and alkyl halides are water-insoluble. Supplementary test such as solubility in hydrochloric acid, then sodium hydroxide, sodium bicarbonate, and finally tested in sulfuric acid must be done accordingly. Solubility in one or more of these acids and bases is defined in terms of the compound being more soluble in base or acid than in water and reflects the presence of an acidic or basic functional group in the water-insoluble unknown compound. Methodology The experiment was divided into two parts and the group was given three unknowns. The first part was for the preliminary test. Data were recorded according to the physical state, color, and odor of the compound. Small amount of the test compounds, copper nitrate, acetic acid also the unknowns were placed in separate porcelain crucible. It was then heated and covered. Observations were noted. If residues were sighted it was tested for acidity or basicity using a drop of distilled water and a litmus paper. Also, a drop of 15% HCl was added to determine if there was formation of gas. Lastly, flame test using a nichrome wire was also observed in order to determine if metals were present. For the second part of the experiment, solubility class test. 1mL of the solvents; water, ether, HCl, NaOH, NaHCO3, and H2SO4, were placed on separate micro test tubes. A drop or pinch of the test compounds; butyl bromide, ethanol, sucrose, butyraldeyde, ethanoic acid, methylamine, nitrophenol, diethyl ether, benzoic acid, propanone, and the unknowns, were added to the solvent. It was then mixed and observed if it dissolved or not, miscible or not, or if there are discoloration present. The solubility flow chart was used in order to classify the compounds. Results and Discussion Preliminary test determines the physical state, color, odor, and the combustion reaction of the compound during ignition. It is shown in Table 1. That copper nitrate which is blue liquid has an odorless smell while it produces a green flame when it is ignited. On the other hand, an organic compound, acetic acid, is liquid and is colorless. It has a sour smell and it produces no residue when it is ignited. With respect with our group samples, all are in liquid state while differs in odor. A1 has a very foul odor, while A2 possess an alcohol like then A3 have a strong odor. A1 and A3 does not have a residue after it was heated it only evaporated and evolution of smelly (unpleasant) gas was also observed. In the case of A2 there were close to black residue and after ignition, a red flame was observed. Table 1 Preliminary Examination Data X| Cu(NO3)2| C2H4O2| A1| A2| A3| A| Liquid| Liquid| Liquid| Liquid| Liquid| B| Blue| Colorless| Colorless| Colorless| Colorless| C| odorless| sour| foul| Alcohol like| Strong| D| Green flame| orange| No residue| red| orange| X – compounds, A – physical state, B – color, C – odor, D – ignition test| Copper nitrate and acetic acid are both in liquid phase. Normally, an organic compound such as acetic acid is a colorless liquid. Copper nitrate, on the other hand, is in aqueous form. Although they are in the same phase, it doesn’t mean that they have the same volatility and solubility. Upon ignition , their volatility differences are noticed. The presence of ash is observed in copper nitrate while on acetic acid there is no present. It is an indication that there was solid present in copper nitrate solution. Since a solid is not volatile, we can easily identify the presence of solid upon ignition. Thus, it is an indication that the physical state of copper nitrate is actually solid. Finally, copper nitrate has color while acetic acid has none. It is because of the presence of metal in the aqueous copper nitrate. While for our unknowns, it was all in liquid form which has an ammonia-like smell A1, alcohol like smell A2 and strong smell A3. By that, the one will know that A1 is already an amine. When it is ignited, it produces no ash and no soot. It is an indication that there is no metal present. Also, we found out that it was an organic compound because the observation was similar with acetic acid. By all obtained observation, it is possible that A1 is an amine. For A2, it was observed that it contains metal, for the reason that when it ignited the flame was red with that we could say that it is a salt. Unknown A3, was found out to be an organic compound because the observation was similar with acetic acid. We can't determine the compound with just preliminary test due to the insufficient data.

(Table 2. can identify the intermolecular forces of attraction and polarity from the structure and the functional group) Since water is a polar compound (possesses hydrogen bond) it is a poor solvent for saturated hydrocarbons. As we all know, saturated hydrocarbons are not polar because they only posses Van der Waals intermolecular force. Due to long chains (or high molecular weights) do not affect by polarity greatly; unsaturated hydrocarbons such as aromatic hydrocarbons have similar solubility with saturated hydrocarbons. The introduction of halogen atoms does not alter the polarity appreciably. It does no increase the molecular weight, and for this reason, the water solubility falls off. On the other hand, salts are extremely polar, the ones encountered in this work generally being water soluble.

The amines probably owe their abnormally high solubility to their tendency to form hydrogen-bonded complexes with water molecules. This theory is also linked with the fact that the solubility of amines diminishes as the basicity decreases. It also explains the observation that many tertiary amines are more soluble in cold than hot water. Apparently at lower temperatures, the solubility of the hydrate is involved whereas at higher temperatures the hydrate is unstable and the solubility measures are that of the free amine. Ethers, esters, ketones, aldehydes, alcohols, nitriles, amines, acids and amines may be considered together with respect to water solubility. Due to their similarity in structure with water, their solubility is high. For that, the solute-solvent interaction is strong because of their compatibility made possible by their common polarity. Because of the polar nature of water; compounds owe their solubility in it almost entirely to the polar groups which they may contain. The functional groups stated above are hydrophilic. As the hydrocarbon percentage increases, the hydrophobic part also increases. As a result, the solubility in water of these compounds containing functional groups, decreases as the hydrocarbon chain is getting longer or the ring is present. The tendency of certain oxygen-containing compounds to form hydrates also contributes to water solubility. The stability of this hydrate is therefore, a factor in determining water and ether solubility. These compounds have great solubility in water because of their capability to form hydrates. It is the reason why diethyl ether and propanone are soluble in water. On the other hand, although generally, aldehydes are soluble in water, butyraldehyde is not. It is due to long chain of the butyl hydrocarbon. For the same reason as for long chains of amines, aromatic alcohols and aromatic carboxylic acid do not exhibit solubility in water. Greater number carbon chains due to ring decreases the effect of polarity. For propanone, it doesn’t just dissolve in water. It undergo reaction which is a nucleophilic addition reaction. As a consequence, it yields a diol. As for the compounds that are water soluble, we can still further classify them through their solubility in ether. It is obtained that ethanol, ethanoic acid, methyl amine, propanone are soluble while insoluble compound are sucrose and nitrophenol. Since dipole bond is present on ether groups, it can differentiate short chain ethers, alcohols, carboxylic acid, ketone and amines from carbohydrates. Ethers cannot dissolve carbohydrates, such as sucrose. Thus, it can be classified as class S. Table 2. 3 Structure and Functional Groups of Known Compounds| Compound| Structure| Functional group| Butyl bromide, C4H9Br| | Alkyl halides| Ethanol, C2H5OH| | alcohols| Sucrose, C12H22O11| | Carbohyd-rates| Butyraldehyde| | Aldehydes| Ethanoic acid| | Carboxylic acid| Methyl amine| | Amines| Nitrophenol| | Alcohols| Diethyl ether| | Ethers| Benzoic acid| | Carboxylic acid| Propanone| | Ketone| The water soluble organic compounds that are also soluble in ether are monofunctional group compounds. We can classify their functional group base on their acidity and basicity and it is done with the use of litmus paper. When the blue litmus paper is dropped in the test compounds, only at ethanoic acid the litmus paper changes its color to red while at ethanol, methyl amine, diethyl ether and propanone. On the other hand, when red litmus paper is dropped on the test compounds, only methyl amine turned the R. L. P to blue while it remained at red for ethanol, diethyl ether and propanone. By that, we concluded that, ethanoic acid is an acid, methyl amine is a base while ethanol, diethyl ether and propanone are neutral. In the other realm, water-insoluble compounds such as butyl bromide, butyraldehyde, nitrophenol and benzoic acid are further tested with 5% HCl. It is obtained that none of these compounds are soluble in the dilute HCl. The explanation for this is that the acid can only dissolve are basic amines. Aliphatic amines (of any class) forms salts (a polar compound) when it is mixed with the dilute acid because of its basicity. 5% hydrochloric acid is also polar so they are soluble. Those compounds that dissolve in 5% HCl will probably fall under class B, which are amines. Compounds that are insoluble in 5% HCl (all compounds) are then tested with 5% NaOH. It is observed that only benzoic acid is the only soluble compound. Compounds dissolve in aqueous base solutions because they form sodium salts hat are soluble in aqueous medium. Probably, it is the only compound which is sufficiently acidic to form salt with the dilute base. Upon comparison, carboxylic acid is the functional group which is the most acidic among all organic functional group aside from sulfonic and sulfinic acids. To prove it, we can compare the acid constant of the functional group of each compound tested. The soluble benzoic acid can sti ll be classified as either a strong organic acid and as a weak organic acid. Upon mixing, it is found that it is a strong organic acid because it dissolves with the reagent. Thus, benzoic acid will fall under class A1 The compounds insoluble with 5% NaOH which are the butyraldehyde and butyl bromide and diethyl ether are further categorized. Upon mixing those compounds with the concentrated sulfuric acid, only butyraldehyde dissolves. So, butyraldehyde is on class X, while butyl bromide and diethyl ether are on class N. As we all know, butyraldehyde contains a functional group with oxygen (aldehyde), so it can undergo sulfonation with the concentrated acid. On the other hand, butyl bromide is saturated and has no functional group with O atom so it can’t undergo sulfonation. Thus it is not soluble. Table 3. 1 Solubility Test Data (Unknown) unknown| A | B | C | D | E | F | 1| | | | | | | 2| | | | | | | 3| | | | | | | A – Water, B – Ether, C – HCl, D – NaOH, E- NaHCO3, F- H2SO4 For solubility test of the 3 unknowns of the group, it is on Table 3. 1 and 3. 2, we initially confirm its solubility in water. It is found that A1 and A2 are soluble. From that, we can anticipate that our sample can be a monofunctional group compound with short chain or a carbohydrate or salts. So, the next steps for the water-soluble compounds were to check its solubility with ether. When we mixed ether and our samples were immiscible dissolves. From that, we may say that one is a salt. From the smell of the unknown A1 we already know that it will fall under amine that has a short chain so we stll tested it with litmus paper because amine are basic. It is observed that when red L. P. is exposed in the sample, it turned to blue, whereas the blue L. P. have no color change when it is exposed. It is an indication that our sample is basic. Thus, our assumptions are correct that it is a short-carbon chain, monofunctional amine and it falls under class SB. Table 3. Solubility Test Data (Unknown) unknown| 1| 2| 3| a| | | -| | | b| Pink| -| colorless| c| Sb| S| X| Possible compounds| Monofunctional alcohols, aldehydes, ketones, amides, esters, aromatic amines, nitriles, and amides with five or fewer carbons. | Salts of organic acids; amine hydrochlorides, amino acids, polyfunctional compounds with hydrophilic functional groups, carbohydrates, polyhydroxy compounds, polyb asic acids, etc. | Saturated hydrocarbons, haloalkanes, arylhalides, other deactivated aromatic compounds, diaryl ethers| a – Litmus Paper, b – Phenolphthalein, c – Solubility Class| For A3, being immiscible to water it was tested with HCl, NaOH, NaHCO3, and H2SO4 for its acidity or basicity. Unfortunately, it failed the entire tests so sum it up to a class X compound. Conclusion The objectives of the experiment were obtained. We were able to examine compounds by using the preliminary test. We were able to recognize the solubility class of each known compound given to us with the aid of solubility test. Finally, we were also able to classify organic compounds based on their solubility in some other compounds and on their acidity and basicity. The analysis and identification of organic compound for this particular experiment consists of two parts which are probably adopted from common schemes. This systematic approach enables us to have a precise analysis without spending much reagents, thus it is useful and efficient tool of identifying organic compounds. Both preliminary test and solubility test are considered. We concluded that preliminary test and solubility test are effective ways of classifying organic compounds. In preliminary test, we had seen the different properties of different compound by its physical state, color, odor and ignition test. We had compared the result of our unknown sample with the known ones, and upon comparison, we concluded that our sample is an organic compound which contains no metal. We had differentiated an organic compound from a non organic compound. An organic compound may be in a form of a solid or liquid, may be colored or not depending on the degree of conjugation, produces odor and has no ash during ignition because of the absence of metal. For our unknown sample, the significant observation is that its fishy, ammonia-like smell. Since it is an organic compound, we can say that it is an amine. By the study of solubility data it has been found possible to lay down certain generalizations which often enable one to predict the solubility behavior of a compound merely by inspection of its structural formula. In the solubility test, we found out the different class of the different organic compound. It is obtained that water soluble compounds are compounds which have a short-carbon chain compounds with monofunctional group and are carbohydrates. For ether, it is capable dissolving short-carbon chain compounds due to their common polarity. It is a way of differentiating carbohydrates from that. For those ether-soluble, their classifications are identified based on their acidity or basicity since they are monofunctional. Acidic groups are carboxylic acids, basic groups are amines while neutral groups are alcohols, aldehydes, ketones, and some carboxylic acid derivatives except the acid halides and anhydrides. For those insoluble compounds, a test for solubility with 5% HCl is made to identify strong bases such as amines that have longer chains or aromatic ring. The dilute acid can only form salt with strong bases, to dissolve. On the other hand, 5% NaOH is then used to check for the presence of acidic organic compounds. For acids, they can form salt with strong base such as NaOH, thus making it soluble. The 5% NaHCO3, which is a weak base is used to identify the degree of acidity of those obtained acidic organic compounds. Strong acidic acids are soluble with 5% NaHCO3 while weak organic acids are not. Lastly, neutral compounds with long chains or ring remained. The concentrated sulfuric acid is used in identifying functional group that has O and organic compounds that are unsaturated. Those compounds undergo sulfonation, making it soluble with the reagent. Solubility plays a major role in the identification and characterization of an organic compound. Through certain chemical tests, one can identify an organic compound. These concepts regarding the solubility of organic compounds are primarily applied in identifying the nature and properties of carbon-containing compounds as wells as predicting their behavior and reaction mechanism when allowed to be reacted with specific solvents during different chemical processes.

Research paper on Ethnomusicology Example | Topics and Well Written Essays - 2750 words

On Ethnomusicology - Research Paper Example The CD is one that fuses the Turkish pop scene into a sense of both cultural traditions and modern techniques to create a contemporary style to the rich culture of history. The instrumentation which is used to complete this style includes mandolin, large percussion sections, violins, guitar and a pop beat for the background sound (Putomayo Presents 2011). Musical Style The musical style of both CDs follows the traditional format of the origins of the groups while carrying influences by the rock and Western style of music. The style is then combined with specific sounds that are able to show the content attributed to each area. The attempt made by both artist groups working toward a fusion sound. For instance, in the song, La Difference, there is a fusion of the African and Western instruments. Electrical guitar is used throughout the piece, as well as a background of piano. There is also a pop-rock beat that is used as a secondary part of the rhythm to create stronger movement. The s ong also uses the phrase â€Å"Love is Serabande† in the chorus. This combines the culture of English, French and African cultures, all which are known in the region that Keita has recorded. All of the CD songs follow this same influence, similar to the group of The Middle East. The musical style of Turkish Groove shows the same contemporary influences. The violin serenades and background, mandolin which is used and the strong percussion line are all a part of the Turkish traditional music. This is the strongest part of the songs that are played. This is combined with the Turkish singing that is attributed to singing in the Turkish language. However, there is a back beat that is... The approaches that are now being taken with music combine the concept of fusion with a cultural context. The individual experiences, political and cultural approaches all make a difference in how artists are expressing their music. However, this is combined with a fusion of sounds that are influencing the globe and changing the approach many have to music. More important, there is the ability to have universal themes that artists are interested in, all which are displayed with the individual and political tensions that the artists are aware of and which creates the main similarities used in the music. When looking at the artists of Keita and Putomayo Presents, it can be seen that cultural influences drive forward the music. However, the themes of ending war, re-looking boundaries and of finding peace remain the same for both groups.

Report in auditing Essay Example | Topics and Well Written Essays - 1250 words

Report in auditing - Essay Example The fact that the external auditors will not be able to physically inspect or examine the audit procedures does not comply with the GAAS (Standards of Field Work, No. 3). This standard explicitly requires the auditor's ability to examine, inspect, observe and confirm the accounting information obtained during the audit procedures. Standard No. 3 of GAAS General Standards requires "mental independence" on the part of the auditor, which might not be fulfilled because the acquiring auditing firm's principal partner is a cousin to TPC's CEO. In this situation, the auditor might not be able to give a free and independent opinion and rather be under significant pressure throughout the process. The last situation is entirely in violation of GAAS Standards of Reporting No. 1. This standard requires that the company's financial statements should be in full compliance with the Generally Accepted Accounting Principles (GAAP). However, according to the aforesaid situation, TPC's accounting records have not been prepared in accordance with the GAAP standards. In order to bring the audit in compliance with the GAAS standards, the first action that should be taken is to provide the auditor complete mental freedom to undertake the audit process and independently obtain the information required to carry out the process. This can be done if the influence of auditor's relative is avoided. Another step which is important to be undertaken is that the auditors should be provided an opportunity to perform physical examination wherever possible. Otherwise the auditor will need to mention his inability to perform physical inspection in the report and reflect this fact in his final opinion to bring the audit in compliance with the GAAS standards. Also any corrections in TPC's accounts and financial recording should be made, where possible, so as to

American Political Parties Essay Example | Topics and Well Written Essays - 1500 words

American Political Parties - Essay Example 791, divisions began to grow as Madison urged Jefferson to join him in organizing against Hamilton leading to formation of the Democratic - Republican Party mainly by anti-federalists. The founders of this party included: Madison, Jefferson, Robert Livingstone and George Clinton of New York and Senator Aaron Burr of Virginia. In midterm Congressional elections, the party garnered majority seats in Congress with 65 members. Madison was supported by Virginia, North Carolina, Georgia, New York and Pennsylvania while New England opposed him (Reichley 32). The Democratic - Republican Party appealed to rural population and farmers; it was an agrarian party. It also advocated economic and social equality and liberal ideals. The French revolution also was an issue at the time and its supporters formed democratic societies (Democratic or Republican) and campaigned in 1794 elections for Republicans (Democratic - Republican Party). They were joined by some federalists’ to become majority party in 1795. Washington did not seek reelection for third term thus the 1996 elections pitted Adams a federalist against Jefferson a Republican. The Republican Party was defeated narrowly by Adams with 71 votes against 68. Thomas Pinckney a federalist got 59 votes and Burr (Republican) 30 votes. Jefferson became the vice president (Reichley 39). The party build up organizations to support Republican candidates and in mid elections Republicans garnered majority seats in Congress. In New York, Burr managed to get a uniform vote for the party ticket. The party got support from evangelicals who were Presbyterian New lights. Support also came from converts of rural families in South and Western frontier (Baptists and M ethodists) and Catholics because of it equalitarian ideals (Maisel, 31-75). In 1800 elections Republicans won with narrow margin with Jefferson 73 votes and Aaron Burr 73 votes, Adams 65, Pinckney 64. Due to tie, the winner was decided by House of Representatives whereby

Consumer Behaviour in Action Coursework Example | Topics and Well Written Essays - 500 words

Consumer Behaviour in Action - Coursework Example Need recognition results from imbalance between actual and desired states as a result of a stimulus that motivates the individual to make buying decision (Lamb et al. 2011). Stimulus may be internal such as hunger or external such as an advert. Need may arise if current product malfunctions, runs out or discovery of a more superior product. This prompts the buyer to start the decision process by gathering necessary information. However, if a product is available which satisfies the need, there is no need for information search. Information may be internal or external and depends on whether the buyer is highly involved with the product or not. The level of involvement depends on previous experience, interest, perceived risk, and situation (Lamb et al. 2011). Routine purchases and low-cost goods are low-involvement; therefore, do not require a lot of information. The buyer may even skip searching for information and make purchases. If buyer has previous product experience but is unfamiliar with current brand, he/she may search for little information hence low-involvement. However, if perceived risk is high, the buyer is highly involved thus extensive information is sought (Blythe, 2008). For example, a routine product like hotdog does not require more information while an expensive car or home is a high-involvement product requiring more information. Information can be from: personal sources like family, co-workers, friends; commercial such as advertising, salespeople, displays; public such as newspaper, TV, consumer organisations or experiential such as using the product. Information sought regards price, quality, compatibility, capability, among other attributes. Once buyer gets information, he/she carries out evaluation to determine the right choice among alternatives.
