Chemical Reactions- Sodium Hydroxide A chemical reaction is a change where two or more substances are changed into a new substance. You can identify a chemical reaction by colour change‚ effervescence (bubbles)‚ when light or heat given off‚ and the change is usually irreversible. There are 6 main types of chemical reactions- combustion (often called burning)‚ synthesis‚ decomposition‚ neutralization‚ single replacement and double replacement. A combustion reaction is a reaction with oxygen‚ and

Introduction Chemical Kinetics‚ described as the study of rate of chemical processes‚ varies on many factors to determine the time needed for a reaction to complete. The rate of reaction of a chemical reaction is important‚ as reactions are of little use if the time period needed for the reaction to occur is too lengthy. Many factors influence the rate of a chemical reaction‚ such as temperature‚ concentration and surface area. The order of the reaction is based on the concentration of the reactants

I. Introduction Victoria Chemicals is one of the leading producers of Polypropelene‚ a polymer that is used in many products ranging from carpet fibers‚ automobile automobile components‚ packaging film and more. When Victoria Chemicals started up in 1967 they built two plants‚ one in Merseyside‚ England and one in Rotterdam‚ Holland. Both plants were identical to each other and produced an equal amount of goods. Morris Greystock‚ the controller of the Merseyside plant had notice a decline in

The Inhumane Weapons of Warfare Chemical warfare is a barbaric weapon of war that should be banned from any war situation. Chemical Warfare is using any chemical or chemical mix that can physically or mentally harm a human being. It has been killing people for over 2600 years and was created by Spartans. “They grabbed burning sulfur pitch and threw it over the walls of Athens attempting to fill the city with toxic gas.”[6] They tried this because they had a small army that was trying to take over
