ammonia
trace gases

Answer 1

The correct proportion of each gas in the air is as follows:

- Methane: Small trace amounts (less than 0.0002%)
- Nitrogen: Approximately 78%
- Hydrogen: Very small trace amounts (less than 0.00005%)
- Oxygen: Approximately 21%
- Ammonia: Very small trace amounts (less than 0.00001%)
- Trace gases: Various gases such as carbon dioxide, argon, neon, helium, etc., make up the remaining fraction, collectively referred to as trace gases.
