    i'm basically confused about balancing equations..
    foor example calcium carbonate reacts with nitric acid to form carbon dioxide, water and calcium nitrate right
    so the unbalanced equation would be
    CaCO3+H(NO)3 --> Ca(NO)3 + CO2 + H2O

    then when it's balanced it will be
    CaCO3+2H(NO)3 --> Ca(NO)3 + CO2 + H2O

    i don't understand how that worksm doesnt the 2 in fron of HNO3 MEAN THAT THERE ARE 6 (NO)3s and tht it wont be balance with the 1 (NO)3 on the other side? im confused help!

    It's HNO3 not H(NO)3 and Ca(NO3)2 not Ca(NO)3

    so basically brakets should never be put in to avoid confusion right

    They should only be used to group atoms that are multiplied by the same amount:

    3HNO3 = 3H, 3H, 9O
    H(NO)3 = 1H, 3N, 3O
    HN(O)3 = HNO3 = 1H, 1N, 3O

    oh alright, im still pretty confused but thanks
    how would you balance
    NaHCO3 + H2SO4 -->H2O +CO2 + NA2SO4
    (sodium hydrogen carbonate + sulphuric acid --> water + carbon dioxide + sodium sulphate)

    The way to balance things is to take each atom individually:

    Balance Na: 2NaHCO3 + H2SO4 --> H2O + CO2 + Na2SO4 [two Na on each side]

    Balance H: 2NaHCO3 + H2SO4 --> 2H2O + CO2 + Na2SO4 [four H on each side]

    Balance C: 2NaHCO3 + H2SO4 --> 2H2O + 2CO2 + Na2SO4 [2 C on each side]

    Is now balanced :yep:

    what about oxygen though, there's 10 on one side and 8 on the other
