In addition to a hydrocarbon, what substance must be present in a combustion reaction?

Question

Quizplus · Accepted Answer

A combustion reaction requires an oxidizing agent, typically oxygen, to react with the hydrocarbon fuel. Nitrogen is not necessary for the reaction and is typically a part of the surrounding air. Carbon dioxide and water are products of the combustion reaction, and while they are present during the reaction, they are not required in order for the reaction to occur.
