Question

here's ur question.......​

Answer 1

Answer:

c

Explanation:

valency of cl =1 charge=-1

Mcl2

M+2 Cl2 -2

hence valency of metal =2 charge =+2

PO4 or phosphate charge =-3

M3(PO4)2

M3+6 (PO4)2-6

hence it is stable

please mark me the brainliest

please please please please

Answer 2

As the metal forms chloride of MCl2 this shows they M has 2 valence electrons

the compound H3 PO4 dissociates as H+ and PO4^3-

Hence The formula of the metal phosphate is M3(PO4)2
