Hello dear...
Here is your answer....
a) CaO + H
O --->Ca(OH)
b) It is combination reaction as well as exothermic reaction .
c) It is used for white washing walls to give them finishing.
The reaction results in Calcium hydroxide as it's product , which is also known as slaked lime.When slaked lime is applied on the walls, it slowly reacts with the atmospheric carbon dioxide to form Calcium carbonate, which gives a finishing look to the walls after some days of white washing.
Hope helped...
