If you mean when will the Earth run out of Oxygen, the answer is never. Oxygen is a very common element, and it's pure form in nature is O2. Normally, the air we breathe is a mixture of oxygen and other elements.
Elements cannot be destroyed in chemical reactions and therefore when we breath or burn something we are simply altering pure oxygen and putting it into another compound (Such as when when we burn Natural Gas or methane: CH4(g) + O2(g) → CO(g) + H2(g) + H2O(g)).
Oxygen is a byproduct in plants, and is found in many many chemicals such as water (H2O), so it can be put back into it's natural form through synthetic means as well. when all the trees die...

Why is Earth the only planet with oxygen and how is that no other planet does?
Other planets do have oxygen, but not in as high of concentration as we have here on Earth.
What planet has plenty of oxygen?
Earth has oxygen. But I don't know why you have to call it "free oxygen". It's not really "for free". People have to plant trees in order to receive oxygen. They are the ones that are supposed to be responsible for their lives. Earth supports the humans by giving them a place to plant, that's why it is the only "living planet".
What planets do not have oxygen?
Only Earth has any significant amount of oxygen in its atmosphere.
On earth molecular oxygen is usually a?
Gas?
Which planet has 20 percent oxygen?
Earth
Effects of no oxygen on earth?
Oxygen is main gas of earth. If there is no oxygen in the earth all the life in the earth should die.
Where do you get your oxygen on earth?
we get oxygen from the trees
Why can't earth's oxygen travel through space?
Earth's atmosphere, including the oxygen, is bound to Earth by gravity.
What is the diffenerce of earth and space?
There is oxygen and gravitational force on earth but there is no oxygen and gravitational force
How does oxygen make life sutable on earth?
Oxygen makes it human capable of breathing in earth that's why when there is oxygen, there is life.
Did the primitive Earth have oxygen?
No. Oxygen is not believed to have been present in the early years of Earth's history.
How much oxygen is used by the earth annually?
The oxygen isn't "used by the earth"; it is recycled by organisms. The total amount of oxygen on planet Earth remains more or less constant.
What is the product of photosynthesis that is needed for all life on earth?
That's because with photosynthesis, it is a system of retrieving energy for the sun in which one of its end products is oxygen. Then the oxygen is released into the atmosphere, and living creatures use this oxygen to breathe and stay living.
Is oxygen an alkaline earth metal?
No. Oxygen is a nonmetal.
Was oxygen on Earth before or after life on Earth?
Elemental oxygen did not appear on Earth until some time after life did. In fact, the oxygen was produced by life carrying out photosynthesis. The first organisms on Earth were anaerobic, meaning their life processes did not involve oxygen. To most organisms like this, oxygen was highly toxic.
What was not in the air on earth 3.6 billion years ago?
Oxygen was not present in large amounts in the early atmosphere of Earth.
How would oxygen affect the earth if it was removed?
If oxygen were to be removed from earth, all life forms that require oxygen to survive will die out leaving the earth as we know it baron. Oxygen is vital to our survival, without it we would die.
