I know that one is Co2, but I don't know the other one. Sorry.
Inert gases are the noble gases (He, Ne, Ar, Kr, Xe, and Rn). They used to be called the inert gases until Neil Bartlett proved that you could make compounds out of some of them, so they were renamed "inert" gases.
An inert gas is one that won't react with other gases. You can store inert gases with any other gases - oxygen (an oxidizing gas) and argon (an inert gas) are commonly stored together in industrial settings.
Inert gases.
Helium and argon are used as inert gases in welding.
because in the inert gasses after ionisation electron is free and this gasses use for collection.
Materials used by firefighter are chemical products.
inert gases as helium,neon,argon are used for for the production of light bulbs.nitrogen gas due to its inertness is used to provide inert atmosphere for the production of electronics....
Those are class D fires. They can be very hard to extinguish, and require that they be buried or a special extinguishing agent be used. Those fires are not affected by water.
These inert gases are used in gas tungsten arc welding, and also in gas metal arc welding for the welding of non-ferrous metals. Semi-inert shielding gases, or activeshield gases, include carbon dioxide, oxygen, nitrogen, and hydrogen. These active gases are used with GMAW on ferrous metals.
It can be safely used on electrical fires, it will extinguish burning liquids, and it leaves no residue behind.
SF6 is used in circuit breakers to help extinguish the arc when deenergizing parts of the system. It is a dense inert gas that will deionize the are.
Noble gases used to be called inert gases because until the 1960's no chemical compounds of a noble gas had been made hence they were believed to be completely inert. Now compounds of argon, xenon radon have been made. These are all very reactive. Compounds of helium and neon have not yet been made.
