Answer 1

plaster of paris.
it is used in hospitals for fixing fractures,supporting the bones in right position.
Equation - CaSO4.1/2H2O + 1 1/2H2O ---------> CaSO4.2H2O
                     calcium sulphate hemihydrate             gypsum

Cheers!

Answer 2

1. Compound is Plaster Of Paris   (CaSO4.2H20)

2. Chemical equation for preparation

CaSO4.1/2H20 + 1.5H2O=CaSO4.2H2O

(Gypsum)                        (Water)         (Plaster Of Paris)
