N_2O supports combustion more vigorously than air. Explain.
N_2O decomposes to give O_2 which is about 1/3 of the volume of gases produced (2N_2 + O_2).
2 N _2 O \xrightarrow{\text { Heat }} 2 N _2+ O _2
On the other hand, air contains 1/5th part of O_2 of its volume. Due to larger content of O_2, N_2O supports combustion more vigorously than air.
