  1. You want the numbers for the molecule to add to zero. For example, Mg is in group II so it is +2. Br is -1(group VIIA or 17 depending upon the system you are using), there are two of them for a total if -2. +2 and -2 = 0
    Here are a set of simple rules for helping determine the oxidation state of elements in compounds. Read those and do NH4NO3.

    Try MgBr2 and I expect you can balance it. i got a balancing equation problem i gotta get this to balance Mg(OH)2+ HBr --> MgBr + H20 so far i'v gotten it down to 2Mg(OH)2+ 4HBr --> 2MgBr + 4H20 but it's still not balanced,so can
