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).

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 water or not allowing the product to

The Role of DNA in Protein Synthesis DNA is found in the cells nucleus. It is part of the chromosome of the cell. DNA is the molecule that controls the making of protein. Protein is used for the growth of cells and organisms and also for the repair of cells. Protein is also used as an enzyme to speed up reactions in the body. Because of this DNA is able to control the whole organism. With out DNA and its ability to make protein the cells and eventually the whole organism would die

Abscisic Acid and Stomatal Closure Abscisic acid is a single compound unlike the auxins‚ gibberellins‚ and cytokinins. It was called "abscisin II" originally because it was thought to play a major role in abscission of fruits. Though ABA generally is thought to play mostly inhibitory roles‚ it has many promoting functions as well. In 1963‚ abscisic acid was first identified and characterized by Frederick Addicott and his associates. They were studying compounds responsible for the abscission

SYNTHESIS AND CHEMISTRY OF K2S2O8 ABSTRACT In this experiment‚ a sample of K2S2O8 was prepared by the electrolysis of an aqueous solution of H2SO4 and K2SO4. The peroxodisulfate anion‚ S2O82-‚ was also observed for its ability to serve as a counterion for precipitation by preparing a copper (II) complex by reacting hydrated copper (II) sulfate with ammonium peroxodisulfate in the presence of pyridine. This same ability‚ coupled with its strong oxidizing ability allowed for stabilization of
