Answer 1

$plaster \: of \: paris$
[calcium sulphate hemihydrates]
[CaSO4. 1/2H2O]


on heating gypsum [CaSO4. 2H2O] at 373K, it loses water molecules and become plaster of Paris [POP].
it's is white power and on mixing with H2O it changes to gypsum
CASO4. 1/2H2O + 1X 1/2 H2O -------CASO4. 2H2O.


USES
1.DOCTORS USE POP FOR SUPPORTING FRACTURED BONES.
2.FOR MAKING TOYS, MATERIAL FOR DECORATION.

Answer 2

Hey mate

Here is ur ans

chemical name of POP is Calcium sulphate hemihydrates.

(CaSO4.1/2H2O)

Reaction of POP with water

CaSO4. 1/2H2O. +H2O. ↪CaSO4. 2H2O

In this reaction gypsum is formed (CaSO4.H2O)

Plaster of paris has many uses and it perform Exothermic reaction.It is mainly uses by doctors and in decoration.

Hope my ans satisfied u
