Is air primarily composed of oxygen?

Answer 1

Air is made up of 20.9% oxygen, 79% nitrogen and the 0.1% is all the other gases (helium, hydrogen, neon, ect.). It is possible to separate air into those component parts and concentrate them for other uses.

Answer 2

No, oxygen is not air, but it is an important component of air.

Air is:

• 78.09% nitrogen
• 20.95% oxygen
• 0.93% argon
• 0.039% carbon dioxide

Answer 3

No. The major gas found in air is nitrogen (N2). Oxygen (O2) is the second most abundant gas in air.

Answer 4

Air contain nitrogen (78 %), oxygen (20 %), argon (1 %) and other minor gases.

Answer 5

No, air is primarily composed of nitrogen (about 78%) and oxygen (about 21%). Other gases such as argon, carbon dioxide, and trace amounts of other gases make up the remaining components of air.

Answer 6

It's mostly composed of nitrogen.
