Detailed Solution

Chemical formulae:

(a) Magnesium chloride = MgCl2

For magnesium(Mg), the valency = 2

For chlorine (Cl), the valency = 1

Now criss-cross the symbol with the valency of another element. Thus, the chemical formula will be MgCl2.

(b) Calcium oxide = CaO

(c) Copper nitrate = Cu(NO3)2

(d) Aluminum chloride = AlCl3

(e) Calcium carbonate = CaCO3
