Answer:
Reactants: aluminum and copper chloride.
Products: copper and aluminum chloride.
Explanation:
Let's consider the following equation.
aluminum + copper chloride ⇒ copper + aluminum chloride
Using chemical symbols, this would be:
2 Al + 3 CuCl₂ ⇒ 3 Cu + 2 AlCl₃
The substances to the left of the arrow are the reactants: aluminum and copper chloride.
The substances to the right of the arrow are the products: copper and aluminum chloride.
