Setup the half reactions from the given reaction and balance both simultaneously

Since there's only one reactant from the initial reaction, we can use H2O as another reactant since this reaction occurs in aqueous conditions. This is necessary so we can make 2 half reactions with different reactants.

Half reactions of HBrO(aq) + H2O (l)⟶ Br(aq) + O2(g  are:

HBrO →  Br 

H2O →  O2

  • Balancing this half reactions under acidic conditions follows a particular steps:

Step 1: Balance the non H or O atoms (not necessary)

HBrO →  Br                                           H2O →  O2

Step 2: Balance O by adding H2O on the product side for the 1st eqn. 2nd equation needs 2 Os, add coefficient 2 to H2O
