Experiment 2: IDENTIFICATION OF UNKNOWNS BY TLC AND MP IN COMBINATION Introduction: Thin layer chromatography (TLC) is one of the most valuable techniques in organic chemistry. This is a best method of separating and identifying mixtures of two or more compounds. The separation is accomplished by the distribution of the mixture between two phases: one that is stationary and one that is moving or mobile. Chromatography works on the principle that different compounds will have different

used to test out things like cosmetics‚ drugs‚ food additives‚ supplements‚ household products‚ pesticides‚ and industrial chemicals. Most of the animals are euthanized after they are experimented on due to health effects caused by the inhumane experiment. Basically animals die due to human errors (Buzzle). Thousands of drugs passed on animal tests hurt humans‚ and vice versa. For example the helpful medication of Aspirin fails animal tests‚ but benefits humans. Heart by-pass surgery was held off

Human Experimentation: Okay or Not? My name is Abi Rodriguez‚ I am on the affirmative side‚ and I believe that human experimentation is okay. The claim I have made can be misunderstood for a statement like unethical experimentation is perfectly fine‚ however I do not believe that. I believe that as long as the experimentation is fine as long as it follows the Nuremberg code and is ethical. There are many reasons on why I support ethical human experimentation‚ for example it has saved thousands

Approximately‚ more than 115 million animals worldwide are used in laboratory experiments every year (Humane Society International‚ 2010). Animals‚ from the fruit fly to the mouse‚ are widely used in scientific research. Research is critical for the advancement of medicine‚ leading to increased chances of survival from diseases and improved strategies to prevent them. Without animal experiments‚ transplants‚ diseases‚ cancer‚ and vaccines would not have been advanced. The use of animals can be inevitable

Abortion “Ethical or Unethical” In my paper I will argue on why I feel that abortions are unethical and why they should not be allowed. As you are reading this paper I really hope that I don’t start to contradict myself. Let me begin by saying there are several different reasons why abortions should be prohibited. The first reason why I feel that abortions should be prohibited is because of religious laws. The bible says that “thou shall not kill”. By aborting babies we are disobeying god and

FIRE RESISTANT BALLOON: Materials - 1 matchbox - 1 candle - 1 yellow colored balloon - 1 blue colored balloon - Half a cup of water Procedure: 1. For this experiment‚ the independent variable is whether the balloon is filled with water or not. The dependent variable is what happens to the balloon when it is placed above the lit candle. This is determined by observing the balloon. The constants (control variables) are how much the balloon is inflated and the amount

UNETHICAL ISSUES STIRRED UP BY ALCOHOL COMPANIES The most severe and significant unethical act by Carlsberg is its marketing strategy. Over here‚ we will analyse and interpret a string of unethical marketing activities by Carlsberg. By definition‚ alcohol advertising is one-sided and presents alcohol consumption as a safe and problem-free practice‚ de-emphasizing the potential health risks and negative consequences. • Targeting the young drinkers In 2006‚ Carlsberg spent about US$2

process of distillation. Distillation is the separation of volatile substances mixed with nonvolatile substances by boiling the mixture to alter the phase of the volatile substance. The researchers used the simple distillation set up to conduct the experiment. 25 ml of The Bar Vodka was used and 7 ml of distillate was collected before a temperature of 95 degrees Celsius was reached. Collected distillate was then subjected to a flammability test to confirm ethanol content. The percent ethanol was computed

Alberto Martinez. Unethical Business Practices The modern business world is characterized for being aggressive and competitive. Companies must be alert and always ready to take advantage of opportunities as quickly as possible. If companies are not aggressive enough they risk losing business to other competitors. For all these reasons‚ many people now question whether there is a place for ethics in this highly competitive capitalist
