What are the final products when CaCl2 x 2H20 are heated strongly?

Answer 1

The hydrated CaCl2 is just dehydrated.
CaCl2.2H2O + heat --> CaCl2(s) + 2H2O(g)

Answer 2

So, the result is just Ca and H2O?

Answer 3

No, the result is CaCl2 and H2O. The CaCl2 does not decompose.

Answer 4

Sorry, I understand now. Thanks.

What about write the reaction for the dehydration of CuSO4 . XH20?
