Which option gives the correct decreasing order of gases in dry air?
Answer and explanation
Correct answer: Nitrogen, oxygen, argon, carbon dioxide
In dry air, nitrogen forms the largest share at about 78%, oxygen follows at about 21%, argon is present at just under 1%, and carbon dioxide is present in a much smaller trace amount. Reading these percentages from greatest to least gives nitrogen, oxygen, argon and carbon dioxide. Therefore option D is correct; the other orders place one or more gases incorrectly.
