    Answer: The balanced equation is 2FeCl_{3} + 3MgO \rightarrow Fe_{2}O_{3} + 3MgCl_{2}

    Explanation:

    The given reaction equation is as follows.

    FeCl_{3} + MgO \rightarrow Fe_{2}O_{3} + MgCl_{2}

    Here, number of atoms present on reactant side are as follows.

    • Fe = 1
    • Cl = 3
    • Mg = 1
    • O = 1

    Number of atoms on product side are as follows.

    • Fe = 2
    • Cl = 2
    • Mg = 1
    • O = 3

    To balance this equation, multiply FeCl_{3} by 2 and MgO by 3 on reactant side. Also, multiply MgCl_{2} by 3 on product side. Therefore, the equation can be rewritten as follows.

    2FeCl_{3} + 3MgO \rightarrow Fe_{2}O_{3} + 3MgCl_{2}

    Hence, number of atoms on reactant side are as follows.

    • Fe = 2
    • Cl = 6
    • Mg = 3
    • O = 3


    Number of atoms on product side are as follows.

    • Fe = 2
    • Cl = 6
    • Mg = 3
    • O = 3

    Since, this equation contains same number of atoms on both reactant and product side. Therefore, this equation is now balanced equation.

    Thus, we can conclude that the balanced equation is 2FeCl_{3} + 3MgO \rightarrow Fe_{2}O_{3} + 3MgCl_{2}.
