Step 1. Separate the whole reaction into half-reactions

*ignore H2O(l) and H+

O3(g) O2(g)

Mn2+(aq) MnO2(s)


Step 2. Balance the non-hydrogen and non-oxygen elements first

O3(g) O2(g)

Mn2+(aq) MnO2(s)


Step 3. Balance oxygen by adding H2O to the side that needs oxygen (1 O: 1 H2O)

O3(g) O2(g) + H2O(l)

Mn2+(aq) + 2 H2O(l) MnO2(s)
