When balancing redox reactions using the half-reaction method, several conditions apply. Check all the REQUIRED conditions. When combining half-reactions, you must make sure the total number of electrons in each half cancels out. Oxidizing agents gain electrons. Electrons are reactants in the reduction half-reaction The number of electrons transferred by a reducing agent can be found by counting oxidation numbers. For polyatomic ions, the oxidation number of the central atom is the same as the charge. The total charges of...

Write balanced redox half reactions (assuming acidic conditions) for the conversion of NH4+ to NO3- and NO2- to N2.
In addition to mass balance, oxidation-reduction reactions must be balanced such that the number of electrons lost in the oxidation equals the number of electrons gained in the reduction. This balancing can be done by two methods: the half-reaction method or the oxidation number method. The half-reaction method balances the electrons lost in the oxidation half-reaction with the electrons gained in the reduction half-reaction. In either method H2O(l), OH?(aq), and H+(aq) may be added to complete the mass balance. Which...
Balance the following half-reaction (express your answer as a half-reaction including electrons and phases): E.g. (acidic conditions) NO3- (aq) --> NO2(g)
Balance the following redox reactions by balancing the half reactions and then combine the half reactions to get the overall balanced redox reaction with the lowest possible whole number coefficients. 1. Consider the following unbalanced redox reaction: MnO2(s) + BrO3−(aq) → MnO4−(aq) + Br−(aq) (a) Balance the corresponding half reactions in acidic conditions using the lowest possible whole number coefficients. (Enter coefficients for one and zero. Blanks will be marked incorrect.) MnO2(s) + H2O(l) + OH−(aq) + H+(aq) + e− → MnO4−(aq) + H2O(l) + OH−(aq) + H+(aq)...
