What is generally required in combustion reaction?

Answer and explanation

Correct answer: Oxygen

In combustion, a combustible substance generally reacts with oxygen and releases heat, often with light. Therefore, oxygen is the correct answer. Carbon dioxide does not support combustion, which is why it is used in fire extinguishers. Exam tip: Remember that combustion needs both a fuel and oxygen from air.
