whats is produced Nickel + Copper(II) Chloride

This is a single replacement type reaction and Ni is above Cu in the activity series.

Ni + CuCl2 ==> Cu + NiCl2

To determine what is produced when nickel reacts with copper(II) chloride, we need to examine the chemical equation and balance it first:

Ni + CuCl2 → ?

Since nickel (Ni) is a metal and copper(II) chloride (CuCl2) is a compound, the reaction between them will involve a single displacement or a redox reaction. In this case, nickel will replace the copper ion in copper(II) chloride and form a new compound.

The balanced chemical equation for the reaction is:
Ni + CuCl2 → NiCl2 + Cu

According to the balanced equation, the reaction produces nickel(II) chloride (NiCl2) and copper (Cu). So, nickel(II) chloride and copper are the products when nickel reacts with copper(II) chloride.
