Helium diffusses 4 times as fast as sulfur dioxide.
Sulfur dioxide diffuses at one-quarter the rate of helium
they cause polution
Helium Helium
The gas commonly used in balloons is helium. It is lighter than air, which causes the balloon to float when it is filled with helium.
Helium has 2 protons, 2 neutrons and 2 electrons. The symbol for helium is He and the atomic number is 2.
Sulfur dioxide diffuses at one-quarter the rate of helium
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 has no chemical reaction with carbon dioxide
No. Grass needs oxygen and carbon dioxide to grow and thrive, not helium.
Helium
yes
Helium, Oxygen, Carbon Dioxide (least to most dense)
carbon dioxide
Because, carbon dioxide is heavier than air whereas helium is lighter than air.
They have different condensation points. Oxygen will turn into a liquid at a higher temperature than helium.
