Vedclass · Answer

(C) The reaction between calcium oxide $(CaO)$, also known as quicklime, and water $(H_2O)$ is a highly exothermic combination reaction.The chemical equation for this reaction is: $CaO(s) + H_2O(l) ightarrow Ca(OH)_2(aq) + 	ext{Heat}$.In this process, calcium oxide reacts with water to form calcium hydroxide $(Ca(OH)_2)$, also known as slaked lime.Since this reaction releases a large amount of heat, it is classified as an exothermic reaction.

Calcium oxide reacts vigorously with water to produce:
