Answer 2

Answer:

First, Calcium oxide is added to water to form Calcium Hydroxide.

$Cao + H_{2}O$ ⇒ $Ca(OH)_{2}$

Then, it is applied to walls, where it is exposed to Carbon dioxide to form Calcium Carbonate.

$Ca(OH)_{2} + CO_{2}$ ⇒ $CaCO_{3} + H_{2}O$

Finally, the water evaporates leaving only Calcium Carbonate on the walls.
