1. N ₂ O ₅ 2. N ₂ O 3. NO ₂ 4. NO

Answer: 1. N ₂ O ₅ N₂O , NO and NO₂ are all released by natural processes (soil bacteria, lightning) and by human activity (fuel combustion, fertilisers). N₂O₅ is an unstable solid-forming oxide that is not a common pollutant released in this way. So N₂O₅ is the answer.

Answer: 1. N\(_2\)O\(_5\)

\(\mathrm{N_2O}\), NO and \(\mathrm{NO_2}\) are all released by natural processes (soil bacteria, lightning) and by human activity (fuel combustion, fertilisers). \(\mathrm{N_2O_5}\) is an unstable solid-forming oxide that is not a common pollutant released in this way.

So \(\mathrm{N_2O_5}\) is the answer.
