    Answer:

    See Explanation

    Explanation:

    Let us find the number of moles of each element

    For iron = 2.24g/56 = 0.04 moles

    For oxygen = 0.96 g/16 = 0.06 moles

    Then we divide by the lowest ratio;

    0.04/0.04      and     0.06/0.04

    1                      and     2

    We Thus obtain 1 : 1.5

    Multiplying through by 2 we have; 2 : 3

    The formula of the oxide formed is Fe2O3

    The balanced equation is;

    4Fe + 3O2 ——> 2Fe2O3
