Answer 2

Explanation:

a) This is a displacement reaction.

b) In displacement reactions, a more reactive metal displaces a less reactive metal from its salt solution.

c) Chemical Equation:

CuSO4 + Fe ---> FeSO4 + Cu

From the above experiment we can conclude that iron is more reactive than copper, therefore it is able to displace it from its solution. The end-products of this reaction are iron sulphate solution (green) and copper (reddish brown) left behind sits on the iron nail.
