Stoichiometry

Name:
Stoichiometry
Detailed information:
The branch of chemistry and chemical engineering that deals with the quantities of substances that enter into and are produced by chemical reactions. For example, when methane unites with oxygen in complete combustion, 16 g of methane requires 64 g of oxygen. At the same time 44 g of carbon dioxide and 36 g of water are formed as reaction productions. Every chemical reaction has its characteristic proportions. The methods of obtaining these from chemical formulas, equations, atomic weights, and molecular weights and determination of what and how much is used and produced in chemical processes is the major concern of stoichiometry.
