The formula of the hydrate will be and the name of the compound is copper sulphate heptahydrate.

Explanation:

Water of crystallisation is the number of water molecules that combine chemically in definite molecular proportion with the concerned salt in the crystalline state.

The formula of the hydrate will be and the name of the compound is copper (II) sulphate heptahydrate as there are 7 molecules of water.

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
