Hey dear,

● Answers -
1) Compound X => Calcium oxide
2) Type of reaction => Exothermic reaction

● Reaction -
Calcium oxide (X) reacts with water to form calcium hydroxide.
CaO + H2O --> Ca(OH)2 + ∆

As heat is evolved in this reaction, this is called exothermic reaction.

* CaO is aka quick lime & Ca(OH)2 as slaked lime.

Hope this helped you.
Keep asking..
