Reaction:
Fe + cuso4 = Feso4 + cu

Activity:
1. Make cuso4 solution
2. get an iron nail
3. dip the iron nail into cuso4 solution and leave it for some time
4. after since time you will observe a between color layer forming on the iron nail.
5. That shows that iron is more reactive than copper.

Answer 2

To show that iron is more reactive than copper-

• At first prepare a solution of copper sulphate by dissolving copper sulphates crystals in water.
• We will get a blue colored solution.
• Now, keep an iron nail dipped in this solution.
• After sometime we will see that the colour of solution changes to dirty green and a reddish-brown powder sticks to the nail.
• Copper in copper sulphate is displaced by iron of the nail, and iron sulphate is formed which is green in colour.
• Thus, it shows that iron is more reactive than copper.

The reaction can be written as-

$\rm { Fe_{(iron)} + CuSO_{4(copper \: sulphate)} \longrightarrow FeSo_{4(iron \: sulphate)} + Cu }$
