Answer 2

Yes, the reaction is exothermic and is explained below.

$CaO+CO_{2}$ → $CaCO_{3}$

• Calcium oxide or quick lime is reacted with carbon dioxide gas and calcium carbonate is obtained.
• The formation of this product evolves heat and thus it is an exothermic reaction.
• The backward reaction of this same is an endothermic reaction and thus the decomposition of calcium carbonate with the evolution of carbon dioxide gas absorbs the heat from surroundings and becomes cool.
