4 N-IIIH2C0H2CIIO-IIO-IIH + 9 O20 2 N20 + 8 CIVO2-II + 10 H2O-II

This is an oxidation-reduction (redox) reaction:

4 CII - 8 e- 4 CIV (oxidation)

4 C0 - 16 e- 4 CIV (oxidation)

4 N-III - 12 e- 4 N0 (oxidation)

18 O0 + 36 e- 18 O-II (reduction)

NH2CH2COOH is a reducing agent, NH2CH2COOH is a reducing agent, NH2CH2COOH is a reducing agent, O2 is an oxidizing agent.
