Explanation:
Calcium oxide reacts with water to form calcium hydroxide, also called slaked lime.
Here are the equations for this reaction:
Calcium oxide + water → calcium hydroxide
CaO+H2O→Ca(OH) 2
A lot of heat is produced in the reaction, which may even cause the water to boil.Hence it is a combination reaction as well as exothermic reaction.
since heat is released, therefore it is a chemical change
