When ammonium perchlorate reacts with dilute nitric acid, it forms X and perchloric acid. On heating X, a gaseous product Y is obtained. Identify gas Y.

1. O2
2. N2
3. NO2
4. N2O

Correct answer: N2O

Solution

When ammonium perchlorate reacts with dilute nitric acid, it produces nitrogen gas (N2) and water, but upon heating, the nitrogen gas can further react to form nitrous oxide (N2O), which is the gaseous product Y.
