Mixing O2 with argon in the welding arc can help improve arc stability and penetration. The presence of O2 enhances the heat input and can result in better weld bead shape and quality. However, too much O2 in the mix can lead to increased oxidation and potential porosity in the weld.
No, argon is a monatomic gas, which means it exists as single atoms of argon and does not form molecules like O2 or N2.
Yes, oxygen (O2) is sometimes added to the shielding gas used in tungsten arc welding process to improve arc stability and penetration. However, the addition of oxygen is typically kept at low levels to prevent oxidation of the weld pool and tungsten electrode.
Yes. Argon is chemically inert due to the presence of completely filled orbitals. So it exists as a monoatomic species.
The four most abundant gases in Earth's atmosphere are nitrogen (N2), oxygen (O2), argon (Ar), and carbon dioxide (CO2).
Kinda surprisingly, Argon. N2 = ~78% O2 = ~21% Ar = ~1% (That's very rough!). It's a little surprising because you don't hear much about Argon but then again, it is an extremely stable (unreactive) element so it's not too astonishing to see a fair amount lying around - doing not a lot.

No. Argon is an inert element. Ozone (O3) is produced by electricity from oxygen (O2).
When 85.0 g of CH4 are mixed with 160. g of O2 the limiting reactant is __________. CH4 + 2O2 → CO2 + 2H2O

Yes.Yes.

Hydrogen (H2), oxygen (O2), nitrogen (N2), helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Ra). (H2, O2, and N2 are diatomic elements.)

Compression. Argon is turn to liquid by compression and removing heat. Typically this is done through refrigeration using liquid nitrogen. Most liquid argon is produced in a plant that makes liquid O2,N2 and Ar. It is the rarest of the 3.
The three most common gases in Earth's atmosphere are nitrogen (N2), oxygen (O2), and argon (Ar). Nitrogen makes up about 78% of the atmosphere, oxygen comprises about 21%, and argon is present at about 0.93%.
