An Introduction to Coustion (Burning) Reactions

A coustion reaction is a major class of chemical reactions, commonly referred to as "burning." Coustion usually occurs when a hydrocarbon reacts with oxygen to produce carbon dioxide and water. In the more general sense, coustion involves a reaction between any coustible material and an oxidizer to form an oxidized product. Coustion is an exothermic reaction, so it releases heat, but
