We have to divide the molecule to know the full name:
The first part:
[tex]CaCl_2[/tex]It is a salt that we have to name with the present elements in the formula, as follows: Calcium chloride (this is the proper suffix for this salt).
Then, it is a hydrate, then you only have to count and add the correct prefix:
In this case, there are 7 hydrates, then the correct prefix is hepta.
So, the full name will be A. Calcium chloride heptahydrate.
