Question

Study the figure attatched carefully and select the incorrect statement(s).

I. A white ring is formed which is closer to the hydrochloric acid end of the tube because hydrogen chloride fumes diffuse faster than ammonia.
II. Ratio of number of atoms of ammonia to that of hydrogen chloride which combine to form 3.6138 × 1024 atoms of ammonium chloride is 1 : 3.
III. 3.4 g of ammonia combines with 7.3 g of hydrogen chloride to form 10.7 g of ammonium chloride.
IV. If temperature is increased, white ring will be formed exactly in the middle of the tube.
(Given : Atomic mass of H = 1 u, N = 14 u, Cl = 35.5 u)

Answer 1

Answer:

here

Explanation:

The ring usually forms nearer to the hydrochloric acid end of the tube because hydrogen chloride diffuses more slowly than ammonia. This is because hydrogen chloride has almost twice the molecular weight of ammonia, and the rate of diffusion is inversely proportional to the square root of the molecular mass of the gas.
