Vedclass · Answer

(A) Lord Rayleigh observed that nitrogen obtained from the atmosphere is slightly denser than nitrogen obtained from chemical sources like ammonia or urea. This difference in density is due to the presence of noble gases,primarily $Argon$ $(Ar)$,in atmospheric nitrogen. Since $Argon$ has a higher atomic mass $(39.95 \ u)$ compared to $Nitrogen$ $(28.01 \ u)$,its presence increases the overall density of the atmospheric nitrogen sample.

The density of nitrogen obtained by the liquefaction of air is higher than that of nitrogen obtained by chemical reactions from nitrogenous compounds. This is due to the presence of which gas in the atmospheric nitrogen?
