IntroductionA dehydration reaction of an alcohol results in an alkene. This type of reaction requires an alcohol‚ an acid catalyst and heat. Generally strong concentrated acids‚ like sulfuric acid and phosphoric acid‚ are used as the acid catalyst.The acid catalyst protonates the alcohol‚ to make a much better leaving group. Weakest bases make the best leaving groups‚ so once the alcohol is protonated the leaving group leaves and produces in a carbocation and water. In order to form the double bond

Purpose: Cells produce toxic wastes‚ in this experiment hydrogen peroxide‚ and without some sort of molecule to break it down the cell will die‚ along with the organism itself. However with the aid of an enzyme‚ catalase‚ hydrogen peroxide is able to be broken down into an intermediate and thereafter harmless substances water and oxygen. The goal of this lab is to measure the reaction rate of this process in different substances such as a liver‚ a vegetable‚ and breast tissue. By using variables

Crawling around on eight legs‚ are some of the most fascinating invertebrates on earth‚ spiders. There are approximately 40000 known species of spiders. Of the 40000 species‚ only a few are dangerous to humans. Spiders belong to the Arachnid class‚ which contains scorpions‚ ticks‚ mites. These creepy creatures live on every continent except Antarctica. They could live around anywhere‚ even in water‚ where food lies nearby. They differ from insects in several ways. They crawl on 8 legs rather than

Experiment 1 The Nature and Properties of Solutions INTRODUCTION The experiment aimed to describe the various ways of expressing the concentration of solutions; prepare solutions of definite concentrations from standard substances by dilution and solve problems involving preparation of solutions and their concentrations. BACKGROUND INFORMATION A solution is any homogenous mixture of two or more substances‚ the relative properties of which may vary within certain limits. The two components

The purpose of our experiment was to synthesize aspirin from acetyl anhydride‚ salicylic acid‚ and sulfuric acid. And then determine the relative purity of the synthesized sample. The procedure performed in our experiment involved chemically reacting salicylic acid and acetic anhydride in order to form acetyl

Isolation of exosomes from human serum The initial volume of serum for the experiments was 4 mL per sample. The samples were diluted with an equal volume of PBS (AppliChem‚ St. Louis‚ MO) to decrease the viscosity. The diluted serum samples were centrifuged at 2‚000×g for 10 min and 10‚000×g for 30 min at 4 °C to remove dead cells and cell debris. The supernatant was transferred into Ultra-ClearTM tubes (Beckman Coulter‚ Indianapolis‚ IN) and centrifuged at 100‚000×g using a Beckman Optima XL-70
