Identification of Unknown Report Abstract: The purpose of this lab was to determine the identity of an unknown bacteria slant culture. The unknown was identified using differential tests to determine its metabolic and morphology characteristics. Results from the differential tests indicated that unknown culture 5 is Staphylococcus aureus. Introduction: The purpose of this lab was to determine the identity of an unknown bacteria slant culture using a series of differential tests. The tests

SYNTHESIS OF ESTERS USING GREEN AND NON-GREEN CHEMISTRY Abstract Esters are a class of organic compounds with the general formula RCOOR’. Ester also contributes the flavor and aromas in fruits and flowers. The esterification reactions will use in the procedure‚ which are the interaction of a carboxylic acid with an alcohol‚ aided by an inorganic acid catalyst (H2SO4). Moreover‚ the green method will not use any catalyst but using heating source instead (microwave). Based on the comparison of

Unknown Lab Report April 25th‚ 2006 Introduction The purpose of this lab was to identify two unknown bacteria cultures using various differential tests. The identification of these unknown cultures was accomplished by separating and differentiating possible bacteria based on specific biochemical characteristics. Whether the tests performed identified specific enzymatic reactions or metabolic pathways‚ each was used in a way to help recognize those specifics and identify the unknown cultures

isopentyl acetate‚ esterification of acetic acid and isopentyl alcohol occurs. Esterification is an equilibrium shift to the product side using an excess of one of the starting components. In this experiment‚ the excess reagent is acetic acid because it is not expensive and can easily be removed for the reaction. The acetic acid and isopentyl alcohol are removed by extraction with sodium bicarbonate and water. The limiting reagent is isopentyl alcohol. A limiting reagent is completely consumed when

An Analysis of the Presence of Alcohol in Ernest Hemingway’s Short Stories Alcohol and Desperation: An Analysis of the Presence of Alcohol in Ernest Hemingway’s Short Stories Throughout the short stories of Ernest Hemingway‚ alcohol inevitably lends its company to situations in which desperation already resides. In an examination of his earlier works‚ such as In Our Time‚ a comparison to later collections reveals the constant presence of alcohol where hopelessness prevails. The

Tanti Lim Thurs AM Unknown Project I. Introduction The purpose to this lab was to isolate and identify two unknown bacteria from a mixed culture provided to us. This study was done by applying all of the methods that have been instructed on thus far in microbiology laboratory class. Each test performed‚ provided us with some key information about the unknown microbes in question . The identification of unknown bacteria is a time honored part of microbiology courses. It will challenge

microbiology‚ the need to identify an unknown microbe may arise. This aids in the recognition of which microbes are harmful or pathogenic as well as those that may be beneficial to us in some way. This report will detail how a similar project was performed in order to identify two unknown micobes using the techniques that were learnt during the course of the semester. We embarked on the project with the knowledge that we would have to identify a Gram(+) as well as a Gram(-) from the species that were given

Introduction: This report required the successful identification of two unknown substances through experimental testing on a selective collection of materials and equipment. For the first substance (which will be either tin or aluminium)‚ two tests shall be done to ensure a decisive and educated decision onto what the substance is. The first step utilizes the dramatic difference in density between the two substances by measuring the volume and mass of the unknown substance. By calculating the volume (through

Executive Summary Alcohol abuse among young people is a serious issue facing society. The Clarity Foundation has developed a strategy to help address this challenge and through a series of initiatives hopes to change the way young people view alcohol abuse and the associated dangers. From a detailed situation and environmental analysis it became clear there were a number of challenges facing this initiative. The most notable challenges involved the attitudes of young people themselves. To effect
