2 CuCl2 (aq) → 2 CuCl (s) + Cl2 (g)

This is an oxidation-reduction (redox) reaction:

2 CuII + 2 e- → 2 CuI (reduction)

2 Cl-I - 2 e- → 2 Cl0 (oxidation)

CuCl2 is an oxidizing agent, CuCl2 is a reducing agent.

This is a precipitation reaction: CuCl is the formed precipitate.

This is a gas evolution reaction, Cl2 is the formed gas.
