Question

A bottle of ammonia and a bottle of dry hydrogen chloride connected through a long
tube are opened simultaneously at both ends, the while ammonium chloride ring first
formed will be:
(a)At the center of the tube
(b)Near the hydrogen chloride bottle
(c)Near the ammonia bottle
(d)Throughout the length of the tube

Answer 1

Answer:

D. throught the long tube

Answer 2

Answer:

NH 3 and HCl from opposite ends of a tube. HCl diffuse slower than NH3 because the mass of HCl is more than the mass of NH3. Since the rate of diffusion is inverse to mass. Therefore, ammonia will travel more distance than HCl at the same time interval and the two gas will first meet nearer to HCl end.

So, the correct option is B
