Answer 2

Answer:

ANSWER

Step-by-step explanation:

3 PbO + 2 NH3 → N2 + 3 H2O + 3 Pb

This is an acid-base reaction (neutralization): PbO is an acid, NH3 is a base.

This is an oxidation-reduction (redox) reaction:

3 PbII + 6 e- → 3 Pb0 (reduction)

2 N-III - 6 e- → 2 N0 (oxidation)

PbO is an oxidizing agent, NH3 is a reducing agent.
