Is O2 also added to shielding gas in tungsten arc welding process?
No, that would defeat the purpose. Shielding gases must be inert (e.g. argon, helium).
How do convert argon to liquid argon?
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.
What is the third most abundant gas in the atmosphere?
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.
When 3.05 of ch4 is mixed with 5.03 moles of o2 the limiting reactants is?
cheaters will not succeed
What noble gases have the most in common?
Sulfide ion (S2- ion) (and not sulfur element) is isoelectronic with argon

Is argon produced by electricity?
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?
When 85.0 g of CH4 are mixed with 160. g of O2 the limiting reactant is __________. CH4 + 2O2 → CO2 + 2H2O

What gases are present in the environment?
21%OXYGEN (O2)78%NITROGEN (N2)0.04%CARBON DIOXIDE (CO2)~0.9%ARGON (Ar)
Do the o2 sensors effect gas mileage?
Yes.Yes.
When 3.05 of ch4 is mixed with 5.03 moles of o2 the limiting reactants is?
cheaters will not succeed
What is the chemical equation for burning lead?
2Pb + O2 ----->2PbO then 2PbO + O2 ------> 2PbO2 some mixed oxide will be formed also 2PbO + PbO2 ----->Pb3O4
What is the gas element at room temperature?
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.)
What noble gases have the most in common?
Sulfide ion (S2- ion) (and not sulfur element) is isoelectronic with argon
Did it appear that CO2 or O2 had a greater effect on modifying the respiratory rate?
CO2
