We are asked to complete the following half-reaction:

O2(g) → H2O(l) (acidic solution and basic solution)

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

O2(g) → H2O(l) + H2O(l)

Step 2: Balance hydrogen by adding H+ to the side that needs hydrogen (1 H: 1 H+)

4H+(aq) + O2(g) → 2 H2O(l)
