heya....
here is ur ans...
x is hydrated Calcium carbonate
( CaCO3.2H2O)
on heating it becomes CaCO3 used to make chalk..that is y
( CaCO3+2H2O)
after that on heating it loses water molecule and forms CaO ( calcium oxide)
that is draying agent..therefore z..
hope helped

Answer: X- CaSO4. 2H2O (gypsum)
Y- CaSO4. 1/2H2O (plaster of paris)
Z- CaSO4
Equation: CaSO4. 2H2O = CaSO4. 1/2 H2O when heated
