$CaO (s) + H_{2} O (l) 🡪 Ca {(OH)}_{2} (aq) + Heat$

What can be inferred from the above reaction?

Open in App

Solution

Calcium oxide CaO is mentioned as (s), hence it is in a solid state.

Water $H_{2} O$ is mentioned as (l), hence it is in a liquid state and not in the vapour state.

Calcium hydroxide $C a {(O H)}_{2}$ is mentioned as (aq) since it forms a solution with water.

Heat is released in the reaction so it is an exothermic reaction.
