EXERCISE 11 Synthesis of Aspirin (Acetylsalicylic Acid from Salicylic Acid) RAQUID‚ Rency J Group 5 18L I. Introduction Due to the demand of certain reagents in the laboratory in order to perform and conduct further experiments or produce essential compounds‚ chemists continuously develop organic synthesis. This process aims to prepare and synthesize desired organic compounds from commercially or readily available ones by providing the simplest route in synthesizing the compound

Determination of Chemical Formulae: The Reaction of Zinc and Iodine By Sarah Abstract: The main objective of this experiment was to use to the reaction between zinc and iodine to examine the validity of the Law of Conservation of Mass and the Law of Constant Composition. The Law of Constant Composition was tested by determining the mass of each of the reactants‚ zinc and iodine‚ and comparing their total to the mass of the zinc iodide product plus the excess zinc. The total mass of the reactants

Introduction The reference of America as the melting pot results from the fact that the country has many of its people coming from everywhere across the world and thus bringing with them different customs‚ beliefs‚ and cultures that should be assimilated to one. The purpose of the assimilation of the different cultures and customs is to make America a one nation. However‚ this is in contrary to the common belief since America is actually not a ‘melting pot’. Most researchers instead argue that America

In the article‚ Why are Starfish ‘Melting’‚ by Jane J. Lee‚ they explain that millions of starfish‚ for the past year and a half‚ have had a lethal virus which has turned them to white goo. The virus is a kind of parvovirus‚ which is “the group of viruses that cause gastroinintestical problems in unvaccintated dogs.” Although this virus is killing many starfish there isn’t very much that researchers can to to try to stop it.

Name: Name of lab partner: Date: Title: Determination of the valency of magnesium Objective: To study the quantitative relationship between the amount of reactant and products of a reaction. A known starting mass of magnesium and the measured collection of hydrogen gas will be used to determine the reaction stoichiometry and the valency of magnesium. Introduction: In Chemistry‚ stoichiometry is the study of the quantitative relationship between amounts of reactants and products of a reaction

America today is thought to be the melting pot of the free‚ where people from far and wide can come to enjoy a life of ease. As what Jimmy Carter says “We become not a melting pot but a beautiful mosaic. Different people‚ different beliefs‚ different yearnings‚ different hopes‚ different dream”. Although it may seem nice to have a true melting pot society‚ times have drastically changed since this theory was coined together in the 1780’s. America still has a long way to go until it achieves the

the President’s Council on Bioethics published the ‘Controversies in the Determination of Death’. Within the publication‚ the Council discusses the various criterions that need to be met in order for death to be declared. The criterions include those of a neurological level‚ which have been observed for over three decades. Although there have recently been objections to the neurological criterion in regards to death determination‚ the Council decided to maintain the criterion. In keeping the neurological

Determination of blood type Introduction: A blood type is a classification of blood based on the present or absence of inherited antigens substances on the surface of RBCs‚ these antigens are made by proteins‚ carbohydrates‚ and glycolipid‚ Now there are total of 8 blood type known for the international society of blood transfers ( ISBT)‚ Also 600 antigens are known for ISBT‚ Antigens are a type of protein (Y shaped) found in blood and it has a great role in the immune system to recognize any
