###### FREE Expert Solution

We are being asked to balance the given oxidation-reduction reaction in basic media:

PbO(s) + NH3(aq) → N2(g) + Pb(s)

The reaction is under acidic conditionsWhen balancing redox reactions under acidic conditions, we will follow the following steps.

Step 1: Separate the whole reaction into two half-reactions

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

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

Step 4: Balance hydrogen by adding Hto the side that needs hydrogen (1 H: 1 H+)
