Answer 1

Answer:

Displacement Reaction occurs when a more reactive metal displaces a less reactive metal from its salt solution.

(a) Yes it will, as Zinc is more reactive than Copper.

          Zn +  CuSO4(aq)  → ZnSO4(aq) + Cu

(b) No, as  Magnesium is less reactive than Calcium

(c) Yes, as Zinc is more reactive than Iron.

     Zn + FeSO4(aq) → ZnSO4(aq) + Fe

(d) No, as Calcium is less reactive than Sodium

Hope it gives you your answer :)

PS - You can mark it brainliest, if you think its correct, so that it stays on top and may help others too. :)
