Question

when a gas jar full of air is placed upside down on a gas jar full of bromine vapours, the red brovapours of bromide from the lower jar go upward into the jar containing air. in this experiment :(a)Bothair and bromide have the same density (b)Air is heavier than bromide (c)Bromide cannot be heavier than air because it is going upwards against gravity (d)Bromine is heavier than air

Answer 1

The red-brown vapors of bromine from the lower jar go upward into the jar containing air because:

(d) Bromine is heavier than air

• Since Bromine is heavier in comparison to the air, it goes upwards into the jar containing air due to the process of diffusion.

• Similarly, air from the upper jar also diffuses into the lower jar.

Answer 2

Answer:

bromine is lighter

Explanation:

that is why it goes upwards lol
