Question

THE OXIDE OF A METAL HAS THE FORMULA MO WHAT WILL BE THE FORMULA OF ITS SULPHATE AND ITS NITRATE.

Answer 1

Answer:

It is given in the question that formula of metal oxide is MO.

As we know the valency of oxygen is 2,

If we make the formula of compound then we criss cross the valency of elements, and if their valency is same they got cancel. So the valency of the metal in this question is 2.

For formula of its phosphate, first of all we know that the formula of phosphate is PO4 3-

Now formula of its phosphate would be as the valency of metalis 2 it would go to phosphate and valency of phosphate that is 3 would go to metal (criss cross)

So formula is M3(PO4)2.

Answer 2

Answer:

Explanation:

M oxide is MO.

O has a 2- charge, so to balance the chemical formula, M has to be 2+.

Sulphate is a polyatomic ion, SO4(2-), so it should be MSO4. The +2 & -2 cancel out producing a neutral compound.
