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..
