Which of the following is a combustion reaction? Key Concept: Reaction types. Three reaction types are decomposition, combination, combustion. Decomposition occurs when a single compound breaks up into two or more compounds. Combination reactions occurs when two compounds become a single compound. Combustion occurs when a compound reacts rapidly with oxygen. With carbon containing compounds carbon dioxide and water are often produced.
