A strip of solid palladium metal is put into a beaker of 0.083 M CuCl2 solution. A strip of solid copper metal is put into a beaker of 0.031 M KCl solution.

Answer 1

In both situations, a chemical reaction occurs when a strip of metal is placed into a solution. The chemical equations for these reactions are provided.

Step-by-step explanation:

situation 1: A strip of solid palladium metal is placed into a beaker of 0.083 M CuCl2 solution. This situation will result in a chemical reaction. The chemical equation for this reaction is:

Pd(s) + 2CuCl2(aq) → PdCl2(aq) + 2Cu(s)

situation 2: A strip of solid copper metal is placed into a beaker of 0.031 M KCl solution. This situation will also result in a chemical reaction. The chemical equation for this reaction is:

Cu(s) + 2KCl(aq) → CuCl2(aq) + 2K(s)
