    @alphakodiak16 7 лет назад +12

    These seem simpler - I don't have single molecules in the reactions I'm attempting to equalize.
    I got really lost with H3AsO4 + KBrO3 + HCl ---> KCl + HBr + H3AsO4 , up until I realized that I've miscalculated the number of electrons given by As (-2e) and received by Br (+6e). After that it was simple: 3H3AsO3 + KBrO3 + HCl ---> KCl + HBr + 3H3AsO4
    Make sure you double-check everything, then triple check, cause even the simplest equation goes to s%^t if you miss something.
