Question

When testing the effect of molecular weight on diffusion, the hydrochloric acid and ammonia molecules were placed at different ends of a sealed tube. The ammonium chloride that formed when the molecules diffused towards each other and met was closer to the ammonia end of the tube.
a. True

b. False

Answer 1

Answer: False

Explanation:

The diffusion can be defined as the movement of the gases having higher concentration moves to the region having lower concentration.

The movement of the particles is more whose molecular weight is less and the movement of the particles is less who has high molecular mass.

The movement of the ammonia will be more towards the hydrochloric acid because the molecular weight of hydrochloric acid is more as compared to that of the ammonia.
