Experiment #17 Classification of Chemical Substances Prepared for: Dr. Robert O’Reilly By: Kudaibergenov Baizak 20.11.2013 Nazarbayev University Introduction While many thousands of substances are known‚ they can be classified into a few simple categories based on type of bonding that exists among the atoms in the substance. Bonds are chemical forces that hold atoms together to form molecules or compounds. These categories are ionic‚ molecular and metallic substances.

Chemical Bonding and Structure In his essay I will be discussing the scientific background and explanation of chemical bonding and structure‚ I will also be describing the method of injection molding and its benefits and limitations and how it is superior to the previous methods of making plastic. Finally I will also list the implication effect of plastic and its effect (economically and environmentally) A chemical bond is the result of a lure (attraction) between atoms or ions

This experiment was performed to demonstrate a cycle of chemical reactions involving copper. This lab will start with copper as a reactant in the first reaction through a series of five chemical forms of aqueous phase reactions and ending to calculate the percentage of recovered solid copper as a product in the last reaction of the experiment. The experiment resulted in a percent recovery from the cycle of copper reactions of an increase to 139%. . Introduction: The purpose of this experiment is

A Chemical change is any change that results in the formation of a new chemical substance. It is something that everyone learns about in school‚ but never really tries to see it in the real world. We all know the basic examples; baking a cake‚ burning wood… etc. What about the examples that are happening around us. For example‚ the Statue of Liberty has been through a chemical change. It was first a dull brown color‚ and now it is a green color. That happened due to a chemical change. During the

Examination of Water and Wastewater 5210 BIOCHEMICAL OXYGEN DEMAND (BOD)*#(1) 5220 CHEMICAL OXYGEN DEMAND (COD)*#(2) 5220 A. 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

Chemistry Summary The particle theory: 1. Matter is made of tiny particles 2. Particles of matter are in constant motion 3. Particles of matter are held together by very strong electric forces 4. There are empty spaces between the particles of matter that are very large compared to the particles themselves. 5. Each substance has unique particles that are different from the particles of other substances 6. Temperature affects the speed of the particles. The

Chemical Banks – Allocation of Profits Question 1. How will you resolve the due bill controversy? Due Bill Controversy: Metro Division’s service to sell the Due Bill for the Treasury division is not recognized by the Treasury department. While Metro acted like a cost center‚ Treasury acted as profit center. When Metro Bank division reviewed the profit loss statement for the Due Bills‚ it was found that Metro division was incurring loss of $26.50 for each transaction. Consequences of Due
