Explanation / Answer

Q1

a)

Cuprous(II) sulfate --> you can't use the term ous if you do NOT have the lowest oxidation number, for Copper, Cu+1 will be "ous"

b)

Magnesium hexaaquaplatinum(II) --> fine

c)

Merury dioxide --> dioxide has no meaning and no need, since it is +1 charged ( Marcury)

d)

potassium hexacyanocobalt(II) --> fine

e)

potassium hexaamminecobaltate --> ok
