Helium diffuses twice faster as Methane does.
Sulfur dioxide diffuses at one-quarter the rate of helium
Helium diffusses 4 times as fast as sulfur dioxide.
they cause polution
The decay of uranium emits lots of alpha particles and a natural gas pocket tends to be a sealed container underground. Helium is cryogenically distilled out of natural gas to produce the helium.

Helium diffuses twice faster as Methane does.
Not much faster, but it does diffuse faster than helium because it is lighter.
Pretty much nothing. It'll mix with the atmosphere and diffuse. Not a problem unless you have huge amounts in a closed, small space.
Helium does not combine with other elements and pure helium will not have carbon dioxide in it.
No. helium does not produce carbon dioxide
No. Carbon dioxide is heavier than helium.
Helium is lighter than neon and will diffuse faster than neon.
depends on the size of its container and volume of helium filling it
Helium is a gas and will take the shape of the container it is taken
Sulfur dioxide diffuses at one-quarter the rate of helium
