A bottle 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 be
View answer and explanation
Correct option: B
Near the hydrogen chloride bottle.
Option B (Near the hydrogen chloride bottle) is correct because ammonia diffuses faster than hydrogen chloride due to its lower molecular weight, so the ring forms closer to the HCl source.

A quantity of hydrogen gas occupies a volume of at a certain temperature and pressure. What volume would half this mass of hydrogen occupy at triple the absolute temperature and the pressure were one-ninth that of the original gas?
In deriving the kinetic equation we make use of the root mean square speed of the molecules which is:
Consider the following statements for kinetic molecular theory of gases
