Reaction Types

By Tae Graham

Synthesis Reaction

A type of chemical reaction in which two or more simple substances combine to form a more complex product. Reactants are elements or compounds. The product is always a compound.

Decomposition Reaction

The opposite of a synthesis reaction. A complex molecule breaks down to make simpler ones.

Combustion Reaction

When oxygen combines with another compound to form water and carbon dioxide. These reactions are exothermic (they produce heat).

Single Displacement Reaction

When one element trades places with another element in a compound

Double Displacement Reaction

When the anions and cations of two different molecules switch places. They form two entirely different compounds.

Oxidation-Reduction Reaction

involves a transfer of electrons between two species. Any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron.
