Answer 2

$\bold \red{Reaction \: of \: Plaster \: of \: Paris \: and \: water}$

The chemical equation for the reaction of Plaster of Paris and water is:

$\bold{CaSO_4. \frac{1}{2} H_2O + \frac{3}{2} H_2O → CaSO_4.2H_2O}$

As plaster of Paris reacts with water, Gypsum is made by heating. Water is added to dry plaster of Paris powder which soon turns into gypsum.
