Question

write the balance equation of a chemical reaction taking place when quicklime is added to water​

Answer 1

Solution:

When quick lime will react with water is will form slaked lime or Calcium hydroxide with heat

Now reaction :

$CaO(s) \: + \:H_2O\: \rightarrow \: Ca(OH)_2(aq) \: + \: Heat$

Here s stands for solid.

aq stands for aqueous solution

When calcium oxide reacts with water it will form Calcium Hydroxide with evolution of heat. So it's a exothermic reaction also.
