· A chemical reaction is a process generally characterized by a chemical change in which the starting materials (reactants) are different from the products. Chemical reactions tend to involve the motion of electrons, leading to the formation and breaking of chemical bonds.There are several different types of chemical reactions and more than one way of classifying them.
5.4 Some Types of Chemical Reactions. Although there are untold millions of possible chemical reactions, most can be classified into a small number of general reaction types. Classifying reactions has two purposes: it helps us to recognize similarities among them, and it enables us to predict the products of certain reactions.
The chemical reaction was a simple one: hydrogen combining with oxygen to produce water. Many combustion reactions occur with a hydrocarbon, a compound made up solely of carbon and hydrogen. The products of the combustion of hydrocarbons are always carbon dioxide and water.
A chemical equation is a shorthand description of a chemical reaction. The following . equation describes the burning of hydrogen gas to form liquid water. 2H. 2 (g) + O. 2
