Question

The density of nitrogen gas prepared from air is slightly greater than that of nitrogen prepared by a chemical reaction from a compound of nitrogen because of-the presence of which of the following in aerial nitrogen?

• A. $ 6500\overset{\text{o}}{\mathop{\text{A}}}\, $
• B. Argon
• C. Greater amount of nitrogen molecules derived from $ 4814.8\overset{\text{o}}{\mathop{\text{A}}}\, $ isotope
• D. Some nitrogen molecules analogous to $ 5884.3\overset{\text{o}}{\mathop{\text{A}}}\, $

Answer 1

Answer: (B)

Nitrogen prepared from air, contains some argon in it so that it is slightly denser than nitrogen prepared by chemical reaction.
