Question

Name the type of chemical reaction in which calcium oxide reacts with water. Justify your answer by giving balanced chemical equation for the chemical reaction.

Answer 1

The type of chemical reaction is an {exothermic combination reaction}.
When calcium oxide (quicklime) reacts with water, calcium hydroxide (slaked lime) is formed, and heat is released:

$\text{CaO} + \text{H}_2\text{O} \rightarrow \text{Ca(OH)}_2 + \text{Heat}.$
