This represents the reaction between Aluminum (Al) and Copper(II) Chloride (CuCl2).
Aluminum is more reactive than copper, so it will displace copper from its salt solution. The balanced chemical equation for this single displacement reaction is:
\( 2\text{Al} + 3\text{CuCl}_2 \rightarrow 2\text{AlCl}_3 + 3\text{Cu} \)
