Complete the following reaction:

 Pb(s) + CuCl₂(aq) → [[1]] (aq) + [[2]] (s)

A chemical reaction in which a more reactive element displaces a less reactive element from its aqueous salt solution is known as a displacement reaction. Lead is more reactive than copper and hence displaces it from its compounds. The reaction is given as follows:

Pb(s) + CuCl₂(aq) → PbCl₂(aq) + Cu(s)
