What is the correct decreasing order of nitrogen, oxygen and argon in air?
Answer and explanation
Correct answer: Nitrogen, oxygen, argon
In dry air, nitrogen is the most abundant of these gases, oxygen is the second most abundant, and argon is present in a much smaller proportion. Therefore their decreasing order is nitrogen, oxygen and argon, making option B correct. The other sequences either place oxygen first, exaggerate argon’s abundance, or place argon above oxygen.
