Helium is used for Airships and blimps. It also makes your voice squeaky! It is used as an inert gas shield in tungsten inert gas welding of aluminum and magnesium. It is used in mixture for deep diving to prevent nitorgen narcosis (the bends). It is used in cooling processes in some nuclear reactors. Helium dating is used to determine the age of some types of rocks for geological purposes. It is also used to inflate children's balloons.

What does heluim neon and hydrogen have in common?
Helium, neon, and hydrogen are all gases at standard temperature and pressure.
What can be separated by a chemical change?
Intramolecular bonds (such as ionic or covalent bonds) can be broken down by a chemical change.
How is the average density of a heluim balloon be changed to make it rise float at a constant level and sink?
you would have to deacrease the density. By doing so, you can float. I don't know bout constant level, but because the air in the balloon is more dense than outside air, the balloon will sink in air. p.s. i know you s.j.v students are probably reading this :)
