Detailed Solution

ii) Zinc is highly reactive than Fe, so no possibilities of chemical reaction

iii) Hydrogen is highly reactive than silver. So no possibility chemical reaction.

Not possible reactions:

ii) $Z n S O_{4} + F e \to n o r e a c t i o n$

iii) $2 A g + 2 H C l \to no reaction$

Possible chemical reactions:

i) $F e S O_{4} + Z n \to Z n S O_{4} + F e$

iv) $C u S O_{4} + M g \to M g S O_{4} + C u$
