Dylan DiMonda Ms Cameron English 10 10 March 2014 Blood Diamonds Have you ever looked down at your ring and wondered where it came from or how it was mined? On your very finger may be the reason why a war was started in Africa. There are regulations to try and keep these diamonds out of the market but these regulations have loopholes in which these diamonds enter the United States. In discussions of diamonds‚ one controversial issue has been whether or not should be sold in the United States. On

The Western World and blood diamonds- our responsibility We are use to say that a girl’s best friend is a diamond‚ but where does these diamonds come from and do they really just cost a high amount of money? Here in Sweden a diamond ring with a 0.30 ct stone could cost up to 18.000kr. Most of us are ready to pay this price to show our love to our partner. But I do not think as many are ready to pay with a human life. Most of the diamonds does come from war-torn areas in Africa. Could it be any

Batch Reactor Aim/Objective The aim of this experiment is to compare the theoretical conversion for a saponification reaction to the experimentally determined conversion in a batch reactor under constant temperature conditions. Experimental Procedure The first step was to ensure the electrical supply to the rig was turned off and that the Armfield batch reactor was empty and clean. 500mL of 0.1M sodium hydroxide solution was then added manually. The pump and stirrer were then set to

Introduction Chemical oxygen demand (COD) is defined as the amount of a specified oxidant that reacts with the sample under controlled conditions. The quantity of oxidant consumed is expressed in terms of its oxygen equivalence. Because of its unique chemical properties‚ the dichromate ion (Cr2O72–) is the specified oxidant in Methods Section 5220B‚ Section

2014 Lab report #1 on chemical and physical properties/ changes Introduction Summary: The purpose of this experiment is to allow students to understand how to differentiate physical and chemical properties and reactions of matter by observing changes of matters under circumstances. Physical properties are properties of matter that can be observed without changing the composition of the matter‚ including the volume‚ mass‚ color‚ density‚ and shape of it. Chemical properties include the matter’s

Lecture No. 1 Chemical Kinetics 1.1 The Rate of a Reaction Chemical Kinetics is the area of Chemistry that is concerned with the speed‚ rate or mechanism at which a chemical reaction occurs. Reaction Rate is the change in the concentration of a reactant or product with time (i.e. M/s). It measures how fast a reactant is consumed and how fast a product is formed. 1.2 WRITING RATE EXPRESSIONS Consider the following hypothetical reaction. A + 2B ( 3C + D Rate = - rate

Observations of Chemical Changes Purpose: The purpose of this experiment is to predict and examine chemical changes/reactions among common chemicals found in consumer products at a macroscopic level. Procedure: The procedure of this experiment was to carefully mix different chemicals together using the chemical filled pipettes and the 96-well plate and determining what chemical reactions occurred.
