Question
The product formed when CaSO4 is heated at 200 °C:
- Ca and SO2
- Ca and SO3
- CaO and SO3
- CaO and SO2
Hint:
When CaSO4 is heated at 200
C gives CaO & SO3.
The correct answer is: CaO and SO3
Calcium sulphate is an inorganic compound with formula CaSO4.
When CaSO4 is heated at 200 C gives CaO & SO3.
CaSO4 
CaO + SO3
