Answer:
The reaction is there is single step displacement.
Explanation:
The reactivity of chromium metal is higher than the reactivity of nickel metal.
Therefore chromium metal can easily displaces nickel metal from the solution of nickel(ii)sulfate

The balanced reaction is
Cr + NiSO₄ → CrSO₄ + Ni
According to the metal activity series, any metal situated above any other metal in the series can displace it from the salt solution.
In the series, Cr lies above Ni.
So, Cr can easily displace Ni from its salt solution (NiSO₄) to produce its own salt, chromium sulphate (CrSO₄), which is green in colour and Ni.
Cr + NiSO₄ → CrSO₄ + Ni
Nickel is thus displaced from NiSO₄.
