Question

A gas jar of oxygen was invented and placed on top of a gas jar containing nitrogen dioxide.

Show the arrangement of the molecules of the two gases after being left in contract for 15 to 30 minutes

Answer 1

there will be diffusion of gases.

diffusion means movement of gas molecule from higher concentration region to lower concentration region.

in this case NO₂ gas molecule which is heavier than O₂ will diffuse into oxygen jar making it brown coloured from colourless.
