* Activity Series: Nickel (Ni) is more reactive than copper (Cu) in the activity series of metals. This means nickel will displace copper from its compounds.
* Reaction Equation: The correct reaction is:
Ni(s) + CuCl2(aq) → NiCl2(aq) + Cu(s)
* Nickel (Ni) will displace copper (Cu) from the copper(II) chloride solution, forming nickel(II) chloride (NiCl2) and solid copper (Cu).
In Summary: The reaction you described is not possible as written. Nickel will displace copper from its compound, not the other way around.
