Combustion Reactions

Combustion reactions are a type of redox reaction.

Combustion reactions are characterized by the reaction of a substance with O2 to form one or more oxygen-containing compounds, often including water.

Combustion reactions are exothermic (they emit heat).

Compounds containing carbon and hydrogen—or carbon, hydrogen, and oxygen—always form carbon dioxide and water upon combustion.

Other combustion reactions include the reaction of carbon with oxygen to form carbon dioxide.
