A mixture consists of ag pb and fe metals. which of these metals will react with zncl2

none of these metals that is (Ag, Pb and Fe) reacted with ZnCl2

this is because the reaction of the metal with metal compound depend reactivity of the metal in the reactivity series.

In the reactivity series Zn is of higher reactivity as compared to Ag, Pb and Fe, Therefore Ag, Pb, Fe cannot displace Zn from its compound.

Non of these elements in the mixture will react with Zinc chloride (ZnCl2).

This is because; silver, lead and iron are below zinc in the reactivity series and therefore, non of these metals can displace Zinc from is salt (zinc chloride).

Metals higher in the reactivity series have the ability to displace less reactive metals from their salts.
