Pure Oxygen is not found anywhere. It has to be created through a process like electrolysis of water, or fractionally distilling.
Although Oxygen is the 3rd largest abundant element in our Universe (after Hydrogeon and Helium), It is not it is not found in it's purest form because of it's high ability to react with other elements.
Electrolysis of water is one way to produce pure Oxygen
Pure water (H2O) is taken in a large container, and electrolyzed. The Oxygen being negatively charged becomes the Anadode, and the Hydrogen, being the positively charged, becomes the Cathode.
To hold the different elements in their purest form (so they don't interact and become water again) a special container must be used. There are 3 containers, one to hold the water (must be in the middle to allow easy flow), and two empty ones on either side. A battery is used to separate the water into its elements. The positive side of the battery which is linked to a contain will contain Oxygen, and the negative charged side of the battery will contain Hydrogen.
In other words, when you electrolyze water, it separates and becomes pure Oxygen, and Hydrogen which must be kept in different containers to stop them from reacting.
This is one of several ways by which Oxygen can be created in its purest form.
carbon, nitrogen and oxygen
Mixture, because it is mixed with all sorts of chemicals, such as smog, and or pollen.Mixture is NOT a pure substance, because to be a pure substance, it can't be mixed with anything.
oxygen is an example of a pure substance because a pure substance is made up of one kind of matter and it cannot be broken down into smaller parts.
Pure oxygen is a gas at 25 C, regardless of the pressure.
Either deoxidation or reduction would be a suitable word. However, note that from a pure metal, oxygen can not be removed, because none is present.
Oxygen is a diatomic and is O2 if found in nature. It is a gas.
carbon, nitrogen and oxygen
Oxygen is an element and a pure substance.
Oxygen is a naturally occuring element, although people now have the technology to extract it from the air when they have a use for pure oxygen
Oxygen is found as O2 because its outer energy level has 6 electrons. By covalent sharing, stability is achieved.
Yes. Pure oxygen is a fire hazard.
Canisters of pure oxygen can be purchased from chemical supply companies. You can also produce pure oxygen through electrolysis of water into hydrogen and oxygen.
Not naturally on Earth; calcium is too reactive with oxygen and water vapor to remain in a pure form outside a container.
Pure oxygen can be breathed. Pure oxygen is often given to patients in hospital that have low O2 saturation.
PURE OXYGEN pure oxygen mar 20 2008 it was pure oxygen
It burns faster in pure oxygen.
Neither. Oxygen is an element, which is a pure substance and not a mixture.
