A bolttle of dry ammonia and a bottle of dry hydrogen chloride connect

1.	A bolttle of dry ammonia and a bottle of dry hydrogen chloride connected through a long tube are opened simultaneously at both ends, The white ammonium chloride ring first formed will beA. at the centre of the tubeB. near the hydrogen chloride bottleC. near the ammonia bottleD. throughout the length of the tube.
Answer» Correct Answer - B `r prop 1//sqrt(M)`. Molecular mass of HCl (36.5) is greater than that of `NH_(3)`(17), hence HCl will diffuse slowly, i.e., the ring will be formed near the HCl bottle.

The gases obey the different gas laws only theoretically. Practically all of them show some deviation from these laws. These are called real gases. The deviation are maximum under high pressyre and at low temperature. These are comparatively small when the conditions are reversed. It has been found that the easily liquefiable gases show more deviations from the ideal gas beheviour as compared to the gases which are liqufied with diffculty. Gas deviates from ideal gas beheviour because moleculesA. are coloulessB. attract each otherC. contain covalent bondD. show Brownian Movement.

Consider the adjacent diagram. Initially, flask `A` contained oxygen gas at `27^(@)C` and `950 mm` of `Hg`, and flask `B` contained neon gas at `27^(@)C` and `900 mm`. Finally, two flask were joined by means of a narrow tube of negligible volume equipped with a stopcock and gases were allowed to mixup freely.
