8 P (s) + 10 NH4ClO4 (aq) → 5 N2 (g) + 5 Cl2 (g) + 8 H3PO4 (aq) + 8 H2O (l)

This is an oxidation-reduction (redox) reaction:

8 P0 - 40 e- → 8 PV (oxidation)

10 Cl-I - 10 e- → 10 Cl0 (oxidation)

10 NV + 50 e- → 10 N0 (reduction)

P is a reducing agent, NH4ClO4 is a reducing agent, NH4ClO4 is an oxidizing agent.
