  2. Bob has balanced what I suspect is an incorrect equation incorrectly. Check it out.
    4 Na on left and right. OK.
    2 S on left and right. OK.
    12 O on left but 10 on right. not ok.
    6 H on left and 4 on right. not ok.

    I think you (Amanda) must have made a typo in the problem. Are you sure that isn't H2SO4 instead of HSO4?
    2NaOH + H2SO4 ==> Na2SO4 + 2H2O.

    2 Na on left and right. OK.
    1 S on left and right. OK.
    6 O on left and right. OK.
    4 H on left and right. OK.
    All done.
