    Coefficient 2 on HCl

    Balanced equation: CuCl₂ + H₂S → CuS + 2HCI

    Explanation:

    We are required to balance the chemical equation given;

    The equation is;

    CuCl₂ + H₂S → CuS + HCI

    Balancing chemical equations involves putting appropriate coefficients on the products and reactants involved in a chemical reactions. It ensures that the number of atoms of each element is equal; on both sides of a chemical equation.

    In our case;

    To balance the chemical equation, we put coefficients; 1, 1, 1, 2 on CuCl₂, H₂S, CuS and HCl respectively. Therefore, the balanced equation will be;

    CuCl₂ + H₂S → CuS + 2HCI

    The equation now obeys the law of conservation of mass which requires the mass of reactants be equal to the mass of products.
