Question

1. Gas Formula Helium He Methane CHA Oxygen 0₂ Nitrogen N₂ Chlorine Cl₂ Relative atomic or molecular mass 4 ,16, 32 ,28 ,71 Look at the table and answer the following questions. (a) Which two gases will mix fastest? (b) Which gas will take least time to escape from gas syringe? (c) Which gas will diffuse slowest and why? Or (c) An unknown gas diffuses faster than 0₂ and slower than N₂, what can you about its molecular mass?​

Answer 1

Step-by-step explanation:

a) this is for the gases with lowest molecular mass meaning they are light and so move faster and so mix faster

b) The gas taking least time will be Cl2 as it is the heaviest gas and so moves the slowest

c) Same its Cl2 and same reason

d) This will be lighter than oxygen but heavier than nitrogen
