article but because we are using a plagiarism tool online‚ I thought it would consider direct quotes as plagiarism even if I cite the source in my write up. The article I chose is called‚ “Synthesis of a Genius” by George Kauffman and Steven Chooljian. The area of exploration and discovery that I chose was the synthesis of urea in chemistry. Urea was discovered by Friedrich Wohler‚ in 1828. This discovery ultimately changed the belief at the time that only organic compounds can be created from living

Laboratory Exercise #3 Measuring Protein in Solution Abstract The purpose of this lab was to learn about the Biuret assay reaction to determine if it can detect proteins and amino acids; also‚ to understand the process of “salting out” proteins and how to determine the amount of protein in a solution. In order to do so‚ egg white and ammonium sulfate were mixed on ice and then put into the centrifuge. After PBS was added‚ the amount of protein could then be determined. After that‚ 14 test tubes

Lysergic Acid Diethylamide (LSD) was created by chemist Albert Hofmann in Switzerland while attempting to create a blood stimulant. The drug was utilized for psychological experiments for many years and this even led to the military experimenting with it as a biological weapon in the 1960’s. During the 1960’s‚ as a result to the wide dispensing of the drug for experimental purposes‚ it wound up being the “…counterculture used the drug to escape the problems of society…” (LSD: A Short History).

In “Helping Students Use Textual Sources Persuasively‚” Margaret Kantz talks about how individuals should read texts to write a synthesis essay. To write a synthesis essay‚ one should be able to come up with an argument and find information from other sources‚ and use them as proofs to back up the argument. First‚ Kantz talks about the mistakes that students usually make when they write this essay. For instance‚ Shirley made a mistake by reading a repeating and telling the story instead of creating

April Goodson CHEM 242L-002 February 20‚ 2013 Oxidation of Cyclohexanone to Adipic Acid Abstract The cyclic ketone cyclohexanone was oxidized to adipic acid using the oxidizing agent nitric acid. The experiment yielded 0.2667 grams of adipic acid‚ giving a percent yield of 113.97%. Although the product was allowed to dry for one week‚ residual moisture was still present in the sample and a melting point could not be obtained. This error in the experiment either resulted from adding too much

In the reaction mechanism‚ the alpha hydroxyketone’s hydroxylic group attacks the positively charged nitrogen from nitric acid attaching it to the molecule. The nitrogen’s electrons are then kicked off on to the oxygen bearing a positive charge‚ creating water. This process formed an organic nitrate. Next‚ water is used to abstract hydrogen from the positively charged oxygen‚ forming hydronium. A carbonyl is formed as well as nitrogen dioxide gas. Simultaneously the oxygen separates itself from nitrogen
