Expert Solution
Step 1
CuCl2 and Na2S are dissolved in water. So, they represented as (aq).
Molecular equation is
CuCl2 (aq) + Na2S (aq) ---------> CuS (s) + 2 NaCl (aq)
According to solubility rules,
Sulfides are insoluble except 1st group and ammonium ions. So, CuS is insoluble.
So, precipitate is formed in the reaction.
