Discussion
Which of the following gas percentage is maximum in atmosphere?
Answer: B
The gas present in the largest proportion in the atmosphere is nitrogen.
Dry air is about 78% nitrogen and 21% oxygen by volume, with argon close to 1% and carbon dioxide only about 0.04%.
Oxygen is second, well behind nitrogen. Acetylene is not a natural component of air at all; it is a fuel gas made from calcium carbide for welding and cutting. Carbon dioxide, though important for climate, is a trace gas.
