    3 mol of Al

    Explanation:

    In order to produce Fe, from Al, we have to make this reaction:

    2Al + Fe₂O₃ → Al₂O₃ + 2Fe

    Ratio is 2:2

    So, to produce 3 mol of Fe, I need the same amount of Al.

    There have to react 3 moles of aluminium (Al)

    Explanation:

    Step 1: Data given

    Number of moles of Iron (Fe) = 3.0 moles

    Step 2: The balanced equation

    Fe₂O₃ + 2Al → 2Fe + Al₂O₃

    Step 3: Calculate moles of Aluminium (Al) needed

    For 1 mol Fe2O3 consumed, we need 2 moles of Al to produce 2 moles of Fe and 1 mol of Al2O3

    When there are 3 moles of Fe produced, we need 3 moles of Al to be consumed.

    There have to react 3 moles of aluminium (Al)
