Answer:

A

Explanation:

MgCl2 + 2AgF > 2AgCl + MgF2

Nope ratio= 1:2:2:1

So 20cm3 of AgCl will yield 10Cm3 of MgCl2 and 20cm3 of AgF according to gay lussac law.

Ionization of MgCl2

MgCl2--> Mg2+ + 2Cl-

1 :. 1 : 2

10cm3 : 10cm3 : 20cm3

Ionization of 2AgF

2AgF---> Ag2+ + 2F-

2 : 1 : 2

20cm3 10cm3 20cm3

So we started with 10cm3 of Mg ion and 20cm3 of Florida ion
