What are the 5 elements of chemical change?
The five basic types of chemical reactions are
combination, decomposition, single-replacement, double-replacement, and combustion
. Analyzing the reactants and products of a given reaction will allow you to place it into one of these categories.
What are examples of chemical changes?
Rotting, burning, cooking, and rusting
are all further types of chemical changes because they produce substances that are entirely new chemical compounds. For example, burned wood becomes ash, carbon dioxide, and water. When exposed to water, iron becomes a mixture of several hydrated iron oxides and hydroxides.
