Based on the activity series, which one of the reactions below will occur? Mn (s) + NiCl2 (aq) → MnCl2 (aq) + Ni (s) Fe (s) + ZnCl2 (aq) → FeCl2 (aq) + Zn (s) Pb (s) + NiI2 (aq) → PbI2 (aq) + Ni (s) SnBr2 (aq) + Cu (s) → CuBr2 (aq)

Respuesta :

Answer:

The reaction that will occur are:

[tex]Mn(s)+NiCl_{2}(aq)->MnCl_{2}(aq)+Ni(s)[/tex]

Explanation:

In the activity series, a higher metal can displace a lower metal from its salt.

Mn is placed in a higher position than Ni in the activity series. Hence, it is able to displace Ni from its salt  [tex]NiCl_{2}[/tex].

All the other reactions are not feasible based on the activity series.

The link for the activity series I referred is given below:
