Question 10 of 10What type of reaction always has oxygen as a reactant and produces energy?OA. A redox reactionO B. A double-replacement reactionAO c. A combustion reactionO D. A single-replacement reactionSUBMIT

Answer 1

C. A combustion reaction.

Step-by-step explanation:

Let's see why a combustion reaction would be the answer:

A combustion reaction is a reaction in which a substance reacts with oxygen gas, releasing energy in the form of light and heat. Combustion reactions must involve O2 as one reactant.

When a combustion reaction has a hydrocarbon as a reactant (a compound made up solely of carbon and hydrogen), the products of the combustion of hydrocarbons would be carbon dioxide and water. Many hydrocarbons are used as fuel because their combustion releases very large amounts of heat energy.

Based on this logic, the answer would be C. A combustion reaction.
