Yes CFC's are much heavier than air. If you filled a balloon with CFC's, it would drop, not float away.
No, water is heavier than air.
Nitrous Oxide is heavier than air.
Some are heavier, but some are lighter. For example, methane rises but propane sinks.
CFC's are heavier than air and contain chlorine thus they would be part of the group of chemicals in question. In theory most items heavier than air should not be able to reach high altitudes, although very small amounts of this gas have been found in the stratosphere.CFCs are attracted to ultraviolet radiationthey are very stableWhich refrigerant is a chlorine-free refrigerant
Yes, if CFC's should ever leak in a closed environment, you are told to stay as high as you can to stay in the oxygen zone. The CFC's will sink to the floor.
argon is a component of "air" and as such air cannot be lighter than air, only more or less dense, however, judging from atomic masses, yes argon is heavier than nitrogen, oxygen, helium, and hydrogen, but depending on pollutants and other gases (CFC's, HCFC's, etc.) the compound that is air can vary slightly in mass.
Yes solvents are heavier than air
No, water is heavier than air.
Yes, it is heavier than air.
Is natural gas heavier than air
"Heavier than air" refers to airplanes.

An airplane is a heavier than air flying craft
Nitrous Oxide is heavier than air.
Yes,it is heavier than air.It sinks to bottom in air.
Gas is heavier than oxygen. Cold air is heavir than hot air
One is lighter and the other one is heavier. :D
