Answer:

a.)no

Explanation:

answer.a. No, we can't stir a silver nitrate solution with a copper spoon since copper is more reactive than silver. It will displace silver from silver nitrate solution and form copper nitrate.

It shows that iron is more reactive than copper it replaces copper from CuSO4. CuSO4 is blue in colour and FeSO4 is light green in colour. It is a displacement reaction
