What is the importance of the formation of free oxygen?
free oxygen is basically an oxygen-free-radical oxygen breaks into free oxygen under the action of sunlight (ultraviolet rays) these free oxygen are highly reactive and combine with oxygen molecule to give ozone and ozone helps filter the harmful effects of ultraviolet rays also the ozone layer is the basic reason for human survival on earth as the sun is too damaging, that i would have burnt us alive into tandoori human!!!! LOL
The primitive earth's atomsphere did not contain?
Free oxygen
What occurs if the dissolved oxygen of water decreases to zero?
only anaerobic(oxygen free) bacteria survives .
What maintenance is essential for an oxygen delivery system?
The oxygen system should be kept clean and dust-free.
What is the specific weight of oxygen?
well according to my calculations !!OINK OINK !!oxygen has no weight it is free living !!!!
Where does the free oxygen in Earths atmosphere come from?
The free oxygen bubbled up from the oceans.
The primitive earth's atmosphere did not contain water vapor free nitrogen free hydrogen free oxygen inert gases?
free oxygen
What is nascent oxygen?
It is a single oxygen atom, a short-lived free radical of oxygen.
What is free in life?
oxygen
Can we use free oxygen?
no

What is the difference between anoxic and anaerobic condition?
Anaerobic = total absence of free oxygen (O2) or bound oxygen (NO2, NO3) Anoxic = absence of free oxygen, but presence of bound oxygen.
What is inferred to be the main source of the free oxygen that first entered earth?
oxygen producing organisms
Is oxygen mixture or pure substance?
Oxygen is a pure substance. In nature, free oxygen exists as a molecule of two oxygen atoms covalently bonded, O2.
Why is copper heated in an atmosphere of hydrogen to make it oxygen free?
Becuase it heats up and burns like a match then cools and the oxygen rises into the sky like a birdy, then it farts and ends up oxygen free.
What is the method of mining oxygen?
Oxygen is not mined on the planet Earth. It is a free gas in the air. Various minerals ARE mined that contain oxygen.
Why was oxygen absent from earth's early atmosphere?
Oxygen is an extremely chemically active element, which is why things can burn in our current atmosphere. In the early Earth, all the oxygen had reacted with other chemicals in the environment, so that there was no free oxygen. Only later, when photosynthesis was used by green plants, was there a source of free oxygen.
