Balance the following half-reaction (express your answer as a half-reaction including electrons and phases):
E.g.
(acidic conditions) NO3- (aq) --> NO2(g)
The balanced half reaction is :
NO3- (aq) + 2 H+ (aq) +
e-
NO2 (g) + H2O (l)
Explanation
This is a reduction half reaction because oxidation number of nitrogen decreases from +5 (in NO3-) to +4 (in NO2)

Use the half-reaction method to balance each redox reaction occurring in acidic aqueous solution. Cl−(aq)+MnO4−(aq)→Cl2(g)+Mn2+(aq) Express your answer as a chemical equation. Identify all of the phases in your answer.
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...
