Question

Burning of coal is an exothermic reaction.

• A. True
• B. False

Answer 1

The correct option is A True

• Exothermic reaction- The type of reaction in which heat energy is released to get products from the reaction of reactants is known as an exothermic reaction.
• When we burn coal which is made of carbon atoms, it gives carbon dioxide gas with the release of heat energy.
• $\underset{\mathrm{Carbon}\left(\mathrm{Coal}\right)}{\mathrm{C}\left(\mathrm{s}\right)}+\underset{\mathrm{Oxygen}}{{\mathrm{O}}_2\left(\mathrm{g}\right)}\stackrel{\mathrm{burning}}{\to }\underset{\mathrm{Carbon}\mathrm{dioxide}}{{\mathrm{CO}}_2\left(\mathrm{g}\right)}+\mathrm{Heat}$
• Since heat is liberated in the reaction, it is an example of an exothermic reaction.

Hence, the given statement is true.
