1. Identify the Reactants and Products:

* Reactants: CuCl (Copper(I) chloride) and Cl₂ (Chlorine gas)

* Product: CuCl₂ (Copper(II) chloride)

2. Count Atoms on Each Side:

* Cu (Copper): 1 on the left, 1 on the right

* Cl (Chlorine): 1 on the left, 2 on the right

3. Balance the Equation:

* Chlorine (Cl): To balance the chlorine, we need two chlorine atoms on the left side. Place a coefficient of "2" in front of CuCl.

2CuCl + Cl₂ → CuCl₂

* Copper (Cu): Now we have two copper atoms on the left. To balance, place a coefficient of "2" in front of CuCl₂ on the right side.

2CuCl + Cl₂ → 2CuCl₂

Balanced Equation:

The balanced chemical equation is: 2CuCl + Cl₂ → 2CuCl₂
