RESULTS
In this Lab 12 reactions were performed, causing esters to be formed from alcohols reacting with acids. Salicylic acid was reacted with methyl alcohol to produce methyl salicylate. The resulting odor was a mint eucalyptus. Acetic acid was reacted with n-pentyl alcohol to produce n-pentyl acetate. The resulting odor was banna berry like smell. Propanoic acid was reacted with n-pentyl alcohol to produce pentyl propanoate. The resulting odor was watermelon, berry grape like odor. Decanoic acid was reacted with Benzyl alcohol to produce Benzoyl deaconate. The resulting odor was rotten tartar sauce. Propanoic acid was reacted with ethyl alcohol to produce ethyl propanoate. The resulting odor was nail polish/nail salon. Formic acid

Essay about Photosynthesis Formal Lab Report

Introduction The purpose of this lab is to determine which pigments in a plant support or effect photosynthesis, based on starch production, which wavelengths of light are involved in photosynthesis, and identify plant pigments found in a plant leaf by means of paper chromatography. Life on Earth is dependent entirely on the energy from the Sun, not only to keep the planet at a suitable temperature but also to provide the energy required to sustain life. The energy of the Sun, in the form of…

Ethyl Ethanoate Lab

known as ethyl acetate) is an ester, which is an organic compound that is produced by the reaction between an organic acid (acetic acid) and an alcohol (ethanol). This ester is probably the most commonly known and used. Ethyl acetate’s uses include being an artificial flavor or smell, being a solvent in procedures such as decaffeinating tea, and it is also used in nail polish removers and cigarettes. In this lab, ethyl acetate is formed by a process called distillation. The theoretical yield for this…

Catalase Lab

The purpose of this lab was to observe the effect adding catalase to a hydrogen peroxide solution. In the lab, titrations were preformed to determine the amount of hydrogen peroxide remaining after various times. The times used were 10, 30, 60, 120, 180, and 360 seconds. The hydrogen peroxide solution contained hydrogen peroxide, distilled water, and a catalase. After the reaction occurred the rate of reactions of the catalase over the specific period of time was calculated and graphed. In the…

that occur within a living organism in order to maintain life. Energy is not naturally in a form we can use to survive. We must eat, mainly sugars and digest the food. The process is called metabolism. Metabolism consists of all the chemical reactions an organism needs to maintain itself. Metabolism is important because it provides energy to our bodies. This process is necessary to sustain life. Without metabolism living organisms will die. Any errors in the metabolic process it will cause…

Fermentation Lab

Reactants: Glucose and Yeast Organisms in Various Buffers Lilli Powell 13 March 2016 119L-03 Logan Williamson and Joseph Patterson Abstract: Fermentation happens when an anaerobic reaction occurs. This lab was testing to see how different pHs effect the rate of CO2 produced by an anaerobic reaction. Five Smith fermentation tubes had a mixture of glucose and yeast organisms of various different pHs. After the tubes were thoroughly mixed and their pHs tested and recorded, they were set aside…

Essay on Composition of Penny Using Redox Reactions

pennies with redox reactions Introduction: The understanding of oxidation and reduction must be clear to carry out this lab. With the understanding of these concepts we can calculate or hypothesize for the properties of each element or compound. Oxidation involves the gain of electrons of hydrogen or the loss of oxygen or decrease in oxidation state. If zinc completely reacts with HCL, then the theoretical yield of copper should be equivalent to the actual yield. Purpose: In this lab, we will determine…
