Question

formula of chloride of an element is MCI2 . Formula of its oxide is​

Answer 1

Explanation:

The given compound is MCl2 which is the chloride of a metal. Thus, the valency of the metal is 2 since the valency of chloride ion is -1 as could be demonstrated by the cross valency method. We know phosphate radical is PO4 with a valency of -3.

Answer 2

M3(PO4)2 is the oxide of chloride MCL2
