During Reaction 2, did the oxidation state of N change? In real terms, in the common chemistry equation 4NH₃ + 5O₂ → 4NO + 6H₂O, yes, the oxidation state of nitrogen changes. Nitrogen changes from -3 in NH₃ to +2 in NO, meaning nitrogen is oxidized during the reaction.
Short Answer: Yes, N Changes Oxidation State in Reaction 2
If “Reaction 2” refers to the reaction:
4NH₃ + 5O₂ → 4NO + 6H₂O
then the oxidation
