Question

A student placed a Zn rod in FeSO4 solution.After 10 hour when rod was taken out in it was observe that​

Answer 1

Answer:

Chemical equation involved : Zn + FeSo4 --> ZnSO4 + Fe

Zinc displaces iron from solution.

Type of reaction : Displacement reaction.

Answer 2

Answer:

When zinc plate is dipped copper sulphate solution,zinc sulphate is formed and copper is deposited on zinc strip.

Zn

(s)

+CuSO

4

(aq)→ZnSO

4

(aq)+Cu(s)

(Silver whitish) (Blue) (colourless) (Reddish brown)

This reaction shows that zinc is more reactive than copper as it displaces copper from its solution and zinc passes into solution as zinc ions and zinc sulphate solution is formed.
