Question

Which one of the following displacement reactions is not
possible?
Zn + CuSO4 + ZnSO4 + C
u
2. Ag + CuSO4 → A62SO4 + Cu
C
Mg + CuSO4 + MgSO4 + Cu
2Na+ CuSO4 → Na2SO4 + Cu​

Answer 1

Option 2 is the answer
As silver being less reactive can’t displace copper from its salt solution

Answer 2

Answer:

Ag + CuSo4 = A62SO4 +Cu is not possible reaction

Explanation:

Because Ag( Silver) is less reactive than Cu(copper)
