Question

statement M forms the oxides M2 O3 ——————— formula of its phospate ? plz aap muja ya question pura baata sakta ha plz (its urgent)​

Answer 1

Answer:

MPO4

Explanation:

O's valency is 2- .

If M's oxide is M2O3, M's valency will be 3+ .

Phosphate formula --> PO4 3-

So, M's 3+ valency will cancel PO4's 3- valency.

Thus, M's phosphate will be MPO4.

This can also be verified by the metal Aluminium (Al).

It has a valency 3+.

Its oxide is Al2O3.

Its phosphate is AlPO4.

This fits with the metal's assumption M.
