Oxygen reacts spontaneously with quite a few natural and organic compounds at or below place temperature in a procedure named autoxidation.[150] Almost all of the organic and natural compounds that consist of oxygen will not be produced by immediate action of O
The unusually high focus of oxygen gas on Earth is the result of the oxygen cycle. This biogeochemical cycle describes the motion of oxygen in and between its 3 most important reservoirs on Earth: the atmosphere, the biosphere, as well as the lithosphere.

The ozone layer filters out UV, which lowers the opportunity to split O2 molecules from the reduce ambiance (troposphere), in which we Stay.

Auto engines have the ideal circumstances to supply ozone, which happens to be a toxin, so modern-day cars and trucks use catalytic converters to transform O3 back again to O2.

Rust is surely an example of the response of oxygen with iron. The greater active metals cost of home hyperbaric oxygen chamber sort peroxides or superoxides. Fewer active metals and the nonmetals give oxides. Two samples of these reactions are:
Oxygen is definitely the third most frequent component while in the Universe, at the rear of hydrogen and helium. It truly is attained commercially from liquefied air separation vegetation. It can be organized from the laboratory by electrolysis of drinking water.
