    To balance the reaction, we should put a 4 in front of Al

    Explanation:

    Step 1: Data given

    AI+3O2->2AI2O3

    Step 2: Balance the equation

    On the right side we have 2*3 = 6 oxygen atoms

    On the left side we have 3*2 = 6 oxygen atoms as well, so those are on both side balanced

    On the right side we have 2*2 = 4 Al atoms

    On the left side we have only 1 Al atom

    We should multiply this by 4 (place a 4 in front of the Al)

    4AI + 3O2 → 2AI2O3

    Now al atoms are balanced on both sides.
