Step 1 of 2

Given is the complete and balance the equation for the single displacement reaction between potassium (K) and nickel (II) chloride.

Balance the given equation K(s) + NiCl2 (aq) ⟶

Explanation:

We use the single displacement reaction concept in which one reactive metal displace the other less reactive metal from its compound.

Step 2 of 2

In this given reaction K is more reactive than Ni and it can displace the Ni from its compound NiCl2 and form the compound KCl and Ni .

The given balanced equation is given as

2K (s) + NiCl2 (aq) ⟶Ni (s) + 2KCl (aq)

Potassium Nickel(II) Nickel Potassium

Chloride Chloride

Explanation:

As Potassium(K) is the reactive metal and belongs to s-block and Ni is less reactive as compared to K so Ni is displaced by K easily from its compound NiCl2.

Final solution

For single displacement reaction the balanced equation is given as

2K (s) + NiCl2(aq) ⟶Ni (s) + 2KCl (aq)
