I'm guessing you mean O2 gas? This is an elemental compound. It can't be a mixture because it is composed of only 1 element. Hope I helped!
Hi,
The answer is gravity.
The bigger the object is the more are other smaller objects attracted to it. The opposite of gravity is dark energy which keeps objects apart and accelerates expansion of the universe.
Hope this helps.

Answer: 4.35%
Explanation:
Scientists estimate that the current composition of gases in the Earth's atmosphere has been stable for the last 200 million years or so.
If the Earth was formed 4,600 million years ago then the percentage of her age that the atmosphere has been in its composition is:
= 200 / 4,600 * 100%
= 4.35%
