Question

The formula of a metal oxide is MO. Then write the formula of its chloride.

Answer 1

Answer:

Oxide is MO, i.e , M is in +2 oxidation state

∴ Formula of the phosphate is M

Answer 2

Answer:

1. The valency of oxygen is I. e., O².
2. The formula of metal oxide is given as MO.
3. Hence the valency of the given metal must be 2i.e.M²+
4. Valency of chloride is 1 i. e, Cl¹-.
5. Therefore according to crisis - cross method the formula of given metal chloride will be MCl².
