Answer 2

Explanation:

Answer: When Gypsum is heated, it leads to the formation of Plaster of Paris.

Explanation:

Gypsum is a substance of calcium. Its chemical formula is CaSO_4.2H_2O and its chemical name is calcium sulfate dihydrate.

On heating gypsum to around 300-400°C, it gets converted into a white substance called as Plaster of Paris.

The equation for the formation of Plaster of Paris is:

CaSO_4.2H_2O\overset{400^oC}\rightarrow CaSO_4.\frac{1}{2}H_2O+\frac{3}{2}H_2O

Plaster of Paris is used to join cracked bones.
