An iron nail (Fe) is placed into a solution of copper(II) sulfate (CuSO4). After some time, the blue color of the copper(II) sulfate disappears and some copper-colored solid (Cu) is found on the surface of the nail. The solution now contains iron(II) sulfate (FeSO4 ), and the container feels warmer than before the reaction.
