where is oxygen found and how is it made?

Answer 1

you breath in oxygen- and it's everywhere. Air Contains 20.9% Oxygen 78% nitrogen 0.9% Argon and traces of other gases.

ir is passed through one section at high pressure and the adsorbent retains the Nitrogen allowing Oxygen to pass through as produced gas. The other section is in the meantime in regeneration phase by absorption of the Nitrogen and purging with a small quantity of Oxygen to purify the system whilst releasing the pressure.

Answer 2

Oxygen is found as 21% of the Earth's atmosphere.
It is 'made' by Photosynthesis of CO2 in plant life during the daytime. By Photosynthesis, daylight and more so, sunlight, converts CO2 and water taken in by the plants, into carbohydrates (sugars, for their growth and energy) and Oxygen. The oxygen is released into the atmosphere.
During the dark hours (at night), the opposite action takes place where the plants take in oxygen and release CO2.
(This is why flowers are not allowed in hospital wards overnight as the bulid up of CO2, if it can't escape, can possibly suffocate a sick person in their sleep).

Answer 3

Oxygen is found all around us. It is made by plants through the process known as photosynthesis. Plants take in carbon dioxide and water and give out oxygen and glucose.

Answer 4

Oxygen found all over, the place. As part of rust, limestone, alcohol, to name a few. As free oxygen, in the air.

Isn't made as such (excepting nuclear reactions which can make oxygen atoms in the first place), but liberated/'freed' from compounds containing it and other atoms.

examples of natural processes that release it are photosynthesis (which takes carbon-dioxide + water + Sunlight and makes Oxygen + Plant Food)

can be "produced" by man by
cyrogenic distillation

Answer 5

Oxygen comes from plants....it is made by photosyntisis....Photosyntisis is the proccess of the sun and water going into a plant...carbon dioxide gets drawn in withthe sun and water which produces Oxygen.

Answer 6

Oxygen isn't necessarily made: it exists and is the most necessary element/component for life on earth.
It is found both in the atmosphere of the earth and in many of the constituents of the earths' composition.
It was created, supposedly, in the "Big Bang" - probably the start of our universe.

Answer 7

oxygen is all around us, trapped in other compounds or in the air in its most naturally faound state as O2,

the alchemists answer to how it is made is that quite simply anything can be 'made' if you had the technology the arrange the components (electrons,protons, neutrons) in the manner required as all matter is only a mixture of these building blocks in one arrangement or another.

the arrangement of them creates the 'element' in question which then displays chacterisitics as intended when you "made" it.

short answer,

O2 comes from stars, like everything else on earth, as a result of the big bang.

Answer 8

About 21% of air is O2, so this isn't a matter of some scarce element that is hard to prepare. Oxygen can be liquidified from air at low temps.

Answer 9

Oxygen is Oprah Winfrey's Television Network, it is found somewhere on cable and it was made with allot of money

Answer 10

I think oxygen is something along the lines of plants absorbing carbon di-oxide (CO2), and turning it into oxygen (O). Could be wrong, though...
