In a combustion reaction, fuel reacts with which gas?
Answer and explanation
Correct answer: Oxygen
Combustion is a chemical reaction in which a fuel reacts with oxygen and releases energy, usually as heat and sometimes as light. Thus, oxygen is essential for ordinary burning and option B is correct. Nitrogen is present in air but normally does not support combustion, helium is inert, and chlorine is not the gas required for common fuel combustion.
