Answer 1

When quick lime is added to water I.e Cao (s) +H20 then ---------calcium hydroxide is formed i.e Ca (OH)2 and a large amount of heat is released .

IN THIS REACTION THE MATERIALS INVOLVED WERE;

calcium oxide and water.

Procedure ; we have taken a small amount of Cao or quick lime in a beaker .

Slowly added water to this

We felt that there is a change in temperature.

THE TEMPERATURE OF THE BEAKER TURNS WARM

due to evolution of large amount of heat .This reaction is highly exothermic.

Equation;

Cao + H2O ----------------ca (OH)2 + H2
