Answer 1

dense white colour is observed and the beaker becomes hot
CaO + H20 ---> Ca(OH)2 + heat

Answer 2

A fast and vigorous reaction takes place. The beaker becomes hot indicating its exothermic in nature . It is an example of a combination reaction.

> The basic chemical reaction involved in slaking of lime due to adding water and quick lime in the beaker  is given below :-

$CaO (s) + H_{2}O (l) -> Ca(OH)_{2} (aq)$
