Question

A reaction is both an exothermic reaction and combination reaction. Identity this reaction. Tell whether the product of this reaction is acidic or alkaline. Is there any application of this reaction

Answer 1

CaO(calcium oxide) + H2O(water)-- Ca(OH)2 + Heat

It is a combination reaction because two compounds on reaction give one product.

As heat is also evolved during the process, thus it is also an example of exothermic reaction.
