A combustion reaction is a major class of chemical reactions. Combustion usually occurs when a hydrocarbon reacts with oxygen to produce carbon dioxide and water.In the more general sense, combustion involves a reaction between any combustible material and an oxidizer to form an oxidized product.Combustion is an exothermic reaction, so it releases heat, but sometimes the reaction proceeds so slowly that a temperature change is not noticeable.n the more general sense, combustion involves a reaction between any combustible material and an oxidizer to form an oxidized product.
