Question

What type of reaction is burning?

(a) Endothermic reaction

(b) Exothermic reaction

(c) Synthesis reaction

(d) Decomposition reaction

I got this question during an online exam.

I need to ask this question from Fuel Burning in section Steam Power Plant of Energy Engineering

Answer 1

The correct answer is (b) Exothermic reaction

The explanation is: Burning is an exothermic reaction. A fuel is a store of chemical energy that we convert into useful energy to our purposes. For example, we can use the energy stored in natural gas to cook our food. To release this energy, we usually burn the fuel. Burning is a chemical reaction in which the fuel reacts with oxygen gas in air and gives out energy in terms of heat. We call this type of reaction as exothermic reaction.
