odors of some fruits. It can be synthesized by Fischer reaction‚ which is an acid-catalyzed reaction of an alcohol and carboxylic acid. One of the esters known for its characteristic banana flavor is the isoamyl acetate. By using Fischer reaction‚ Isoamyl acetate was produced by refluxing isoamyl alchol and acetic anhydride with the presence of sulfuric acid for 30 minutes. After cooling the mixture‚ cold water was added and it was transferred in a separatory funnel. It was then extracted with immiscible

Synthesis of 1-Bromobutane from 1-Butanol Reference: Discovering Organic Chemistry in the Laboratory; John R. Ganson Ph. D‚ Revised 2011 by Alfredo Mellace Ph. D www.Aldrich.com Purpose: To synthesize 1-bromobutane from 1-butanol via SN2 reaction. Alcohols are converted into the alkyl halides adding an aqueous solution sodium bromide. The sulfuric acid acts as a catalyst in converting the OH functional group of butanol‚ to a better leaving group. In order for this reaction to synthesis 1-Bromobutane

Writing Assignment #3 Based on Wilson’s public declarations‚ why was the United States entering the Great War (WWI)? How was this different from his private declarations? What was Wilson’s plan for the postwar world? Based on Wilson’s public declarations the United States was entering the war because in August 1914‚ President Woodrow Wilson asked Americans to remain impartial in thought and deed toward the war that had just broken out in Europe. Wilson wanted the United States to exemplify

DNA FROM ONIONS ABSTRACT The purpose of the experiment was to experience firsthand the isolation of DNA form a plant tissue without destroying its structure and sequence. A white onion was used for the experiment. After several processes‚ DNA isolate was the visible result. Different chemical tests were performed on the DNA isolate‚ namely: Dische Test‚ Murexide Test‚ Wheeler-Johnson test and Test for Phosphate. Visible results were then noted. INTRODUCTION DNA (deoxyribonucleic acid) was discovered

Magnesium Oxide: Origin‚ Production and Utilization Magnesium oxide is a basic or alkaline kind of earth metal that naturally originates from seawater. The compound is odorless and colorless that makes it difficult to see by the naked eye. To produce such compound‚ extraction from the seawater by electrolysis and several chemical processes id done. The compound is formed from the thermal processes which make uses of air and oxygen. Magnesium hydroxide is also produced. The versatility of uses of

of a Compound: Burning Magnesium Lab Purpose: To experimentally determine the percent composition of a reaction product. Directions: Work in teams of three. The directions for this lab are on a separate sheet of paper at your lab bench. Make sure that everyone in your group understands the process and purpose before you get started. Assign tasks. Everyone in the group will be expected to contribute at the same level of participation‚ and for this experiment‚ each individual will submit
Premium Oxygen Magnesium Combustion
COMBUSTION OF MAGNESIUM OXIDE DESIGN Aim/Purpose: To calculate the number of moles and the empirical formula of magnesium oxide. Safety precautions: 1) Wear lab coat 2) Wear gogles. 3)Make sure the bunsen burner is working properly and their is no leakage. 4) Wear gloves. Hypothesis: The weight of the magnesium ribbon increases after burning‚ so this indicated that their was a change in mass. This change happened because of the magnesium ribbon inside the crucible which reacted with Oxygen

Hypothesis - The idea I aim to test in this experiment is the relationship between the mass of magnesium and mass of oxygen once the magnesium has been heated and reacted with the oxygen. There will be 3 variables in this experiment. The independent variable will be the mass of magnesium ribbon as different measurements will be taken and used for each trial. The dependant variable will be the mass of Magnesium Oxide‚ this is a measured variable as the mass of oxygen can be calculated and will enable

from The Emigrants by Edward Kamau Brathwaite The poem from The Emigrants by Edward Kamau Brathwaite is the thoughts of an indigenous inhabitant‚ the persona‚ thinking of the invasion that has been so abruptly brought upon them which they must now face. We know that the persona is one of the inhabitants because in line four and twelve‚ the repetition of “my” personalizes what is happening‚ coming from an inhabitant’s perspective. The themes perception versus reality‚ power‚ discovery and war
