All types of chemical reactions:

A chemical reaction in which two or more substances combine to form a single product is called a combination reaction or synthesis.

A chemical reaction in which a single compound splits into two or more simple substances is called a decomposition reaction.

Reactions in which the more reactive element displaces the less reactive element from its compound are called displacement reactions.

Reactions in which the ions of the reactants exchange places to form two new compounds are called double displacement reactions.

Reactions which involve the addition of oxygen or the removal of hydrogen are called oxidation reactions.
