There are a numerous ways through which oxygen can be separated from air. One way is through the usage of fractional distillation of air. This is done by lowering the temperature of air while increasing the pressure. When water vapour and liquid air have cooled off, they are extracted as liquids and then the remaining air is cooled further until a temperature of 90K where the liquid oxygen coos off and is collected and stored in an insulated container.

∙ 13y agoPure oxygen is a gas that only contains oxygen - and nothing else. Oxygen is pure when a certain mass (or volume) of it contains no other elements.
As I wrote the above, someone else suggested pure oxygen was pure air. Air on earth is mostly nitrogen (about 75%), 20% oxygen, with smaller amounts of argon, water vapor, CO2, and other gasses.

∙ 15y agoNo. Oxygen is a specific chemical found on the period table, it's the part of the air that we breathe. Air is everything around us, made up of several chemicals, such as oxygen, hydrogen and carbon.

∙ 12y agoOxygen is an elemental gas usually found in the form of O2. Air is the mixture of gasses that make up earth's atmosphere. Oxygen is just one of those gasses, composing about 21% of it by volume. 78% of air is nitrogen and another 1% is composed of a variety of other gasses.

∙ 15y agothere is only about 20.9% oxygen in air. 78.1% is Nitrogen

Are oxygen and gas the same thing?
Yes, you could consider air a gas, but air on earth is more commonly thought of as a collection of gases: oxygen, nitrogen, etc.But on the other side, "gas is air" is not correct. When we talk about "air", we talk about the specific combination of gases that we breathe.In other words, you would not say that a jar full of methane is air, but you could say that a jar full of air is a gas.
What did stromatolites add to the atmosphere?
thats thr thing iu doynhrigf
How much oxygen have you got in the air?
There is 21% of oxygen in the air.
What is the percentage of oxygen in earths air?
21% of the air is oxygen
Why are air bubbles found in dry mount samples?
Usually water is used and the Oxygen in the water gets trapped in between the slide cover and the slide. In this case, the same thing is actually happening, because you have forgotten about air. Air is everywhere, and if that slide cover is not pushed down from one end to the other, then Oxygen and even hydrogen bubbles can get trapped just like the oxygen from the water. Try letting the slide cover fall onto the slide. then gently tap- moving from one side to across the slide to the other to push the Oxygen out. If you randomly tap, more than likely air will be trapped.
How and where do blue whales store air?
Whales store air In their lungs and oxygen in their blood. Humans do the same thing, but we're not as good at as whales.
What process adds oxygen to ocean water?
Recall that plants take carbon dioxide from the air and make oxygen. Ocean plants do the exact same thing.
Is nitrogen the same thing as oxygen?
no
Is air and oxygen are the same gas?
air has oxygen in it but also other gases, e.g. helium nitrogen.
Are carbon and oxygen the same thing?
Carbon and Oxygen are different elements.
Is oxygen and oxidation mean the same thing?
No.
Air not the same as oxygen?
Yes, Air is a mixture of oxygen, nitrogen, carbon dioxide, water vapor, and pollutants.
What is properties of oxygen gas?
It has the same density as air.
Is oxygen the good thing we breathe?
Air is mainly a mix of oxygen and nitrogen. Oxygen is the part your body uses- the good stuff.
Is humidified oxygen the same concentration as regular oxygen?
I want to know is 28% humidified O2 the same as room air?
Is oxone and ozone the same thing?
Ozone can be made in air, or in varying concentrations of oxygen and air. Some salesmen think "new" names are helpful, so this is probably "oxone" = "ozone made in oxygen for a parent gas". When it gives you a headache, it will smell sweeter when doing it.
Are oxygen atoms different to oxygen atoms?
well, they are the same thing unless there are now a isotope
