Answer

Brief Explanations:

Combustion reactions typically involve a hydrocarbon reacting with oxygen to produce carbon - dioxide and water. Oxygen is a reactant, not a product in combustion. Water and carbon - dioxide reacting is not a combustion reaction. Reactions involving ions are not characteristic of combustion reactions.

Answer:

A hydrocarbon reacts with oxygen.
