Question

describe the activity to show that the combination reaction between quick lime and water is an exothermic reaction​

Answer 1

CaO + H2O -----> Ca(OH)2 + Heat.

Here calcium oxide reacts with water to form Calcium Hydroxide gives out heat. In this there Heat along with the product. Hence we can say that it is an Exothermic reaction.

Answer 2

Answer:

When water reacts with quick lime, calcium hydroxide is formed along with release of heat. Thus, it is an exothermic reaction. ... Evaporation of water and sublimation of camphor are examples of endothermic reactions.
