Answer to Question #270809 in Physical Chemistry for Dolphy

Question

Balance the following equations using the change in oxidation number method.

3.NH3+O2⎯→NO+H2O

Balanced equation: _______________________________________________________

Oxidant:

(1 pt) ________________

Reductant:

(1 pt) ________________

Answer 1

4 NH₃ (g) + 5 O₂ (g) → 4 NO (g) + 6 H₂O (l)

This is an oxidation-reduction (redox) reaction:

4 N^-III - 20 e^- → 4 N^II

(oxidation)

10 O⁰ + 20 e^- → 10 O^-II

(reduction)

NH₃ is a reducing agent, O₂ is an oxidizing agent
