Globalization has made a profound change in business and is continuing to happen throughout the world. There has been an “…emergence of completely new social‚ political‚ and business models” (Friedman‚ 2007‚ p. 48). According to Friedman (2007) the

Comparison of Three Isomers of Butanol Introduction An alcohol’s reactivity is determined based on the attachment of their hydroxyl functional group. The location of this hydroxyl functional group will impact the molecular structure of the alcohol‚ making it either primary (1° )‚ secondary (2° )‚ or tertiary (3° ). The purpose of this experiment is to observe and predict the reactions that take place between all three alcohols and an oxidizing agent‚ as well as to test our theories of how the

The Bill of rights The Bill of Rights are rights protected against the government only. They are certain basic rights of the people. They are civil rights and civil liberties that people have to obey because of the Amendments that were introduced by James Madison which makes The Bill of Rights very important and is part of American history. The Amendments are basically clauses that initiate some kind of protection for citizens here in the United States. James Madison became one of the leaders

Experiment #1 Preparation of Ethanol from Sucrose Based on R. Weglein & C.L> Yau‚ CHEM 203 Experiments in Organic Chemistry II Laboratory‚ 5th Edition‚ 2006‚ p29-32. Statement of Purpose: An aqueous solution of ethanol is prepared by the fermentation of sucrose. The percent alcohol is the resulting solution and the percent conversions of the sucrose are to be determined. Introduction: Sucrose is a molecule containing glucose and fructose. http://faculty.tcc.fl.edu/scma/phelpsj/experiments/ethanol

The first reaction time test is the reaction ruler. This test shows the speed of the occipital lobe and the motor cortex of the brain. The faster the reflex the faster the afferent and efferent pathway is. Subjects 1‚ 3 and 5 experienced reaction times that were under the average of 195.167 milliseconds. While Subjects 2‚ 4 and 6 experienced times that were over the average of the population. In general terms it could be said that subjects 1‚3 and 5 have better hand and eye coordination than subjects

A2 Chemistry Coursework Section 1 Aims: I aim to find out the order of reaction with respect to [H2O2] and [2I-]. I aim to find out the activation enthalpy of the reaction by finding the rate of reaction at different temperatures using the Arrhenius Equation. The experiment will go as follows: Into a conical flask put 15cm3 of distilled water and add 2cm3 of [X]moldm-3 potassium iodide (KI) solution and 1cm3 of 2moldm-3 sulphuric acid. Then add to this 2.5cm3 of 5vol (0.42moldm-3) hydrogen

Title: Preparation of Cyclohexene from Cyclohexanol Aim: To prepare an alkene‚ cyclohexene‚ by the dehydration of an alcohol‚ cyclohexanol‚ and better understand the processes that take place during this reaction. Introduction: One of the common ways of preparing an alkene is through the dehydration of an alcohol. In this experiment cyclohexanol is dehydrated to prepare cyclohexene while using sulfuric acid as a catalyst. A bromine test can be later done to ensure that the end product is

The objective of this lab was to prepare n-butyl bromide or n-bromobutane‚ which is derived from an alcohol and an acid. In this case‚ n-butyl alcohol and sulfuric acid were the reagents. There were two methods of distillation that was involved in this experiment. The first was by reflux distillation‚ which is used to speed up a chemical reaction without having the reactants/ products evaporate or explode. Data Table 1 indicates the amount of each reagents that was prepared for the reflux apparatus
