A vanadium pentoxide catalyst is used in order to speed up the reaction
vanadium panta oxide V2O5.
sulphur and oxygen
sulphuric acid

Ammonia.
Ethylene gas is used to accelerate the ripening process of bananas.
Carbon dioxide, Argon, Helium, but not Nitrogen, can be used as 'shielding' gas in Gas Metal Arc Welding.
long slanting tube used in the distilling process is condenser. where hot gas is condensed in to liquid
The splitting of water by the process of photolysis in photosystem II. There the electrons and protons are used in the process of photosynthesis but oxygen gas is a byproduct that diffuses out of the stomata into the atmosphere.
condensation
It is a chemical process.
Separation of what? If it is the separation of East/West Germany then it is because gas masks were used in Gas Warfare, which was used in WWI and WWII.
Ammonia.

By Diffusion.........
long slanting tube used in the distilling process is condenser. where hot gas is condensed in to liquid
because the other half of the oxygen is used for the contact stage
A gas with large molecules has friction between its molecules because they are constantly coming into contact with each other. This is a normal process which does not alter the overall composition or characterises of the gas.
By the Haber process, hydrogen gas reacts with nitrogen gas to produce ammonia.
Argon is used as a protective gas in the process of preparation of silicon crystals.
