    Answer:

    Al2O3 + 3Mg ===》 3MgO + 2Al

    Explanation:

    Reaction of aluminium oxide with magnesium metal would form magnesium oxide and aluminium metal.

    Balancing the stoichiometric equation, the number of atoms at the reactant must be equal to the number of atoms at the product so that law of conservation of matter must hold.

    Al203 + 3Mg ====》 3MgO + 2Al

    2 aluminium at reactant = 2 aluminium at product

    3 oxygen at reactant = 3 oxygen at product

    3 magnesium at reactant = 3 magnesium at product.
