When water is added to calcium oxide (quicklime), it will be converted to calcium hydroxide (slaked lime) with the liberation of enormous amount of heat.
CaO+H₂O=Ca(OH)²+heatCaO+H₂O=Ca(OH)²+heat
*It is an exothermic reaction. Calcium hydroxide is an alkali.

Answer:
CaO is Calcium Oxide,
So, when it reacts with water, I.e, H20, Calcium hydroxide is formed.
CaO + H20 ----> CaOH2 (Calcium hydroxide)
Also this is a combination reaction which is exothermic.
