Inhaled air contains more oxygen than exhaled air. When you breathe in, oxygen is taken into your lungs and absorbed into your bloodstream. When you breathe out, you release carbon dioxide produced by your body and some of the oxygen has been used up.
Oxygen is present in the air due to photosynthesis, where plants and algae use sunlight to convert carbon dioxide into oxygen. This process has been occurring for billions of years, continually replenishing the Earth's atmosphere with oxygen.
Oxygen is a gas that is always present in Earth's atmosphere. It makes up about 21% of the air we breathe and is essential for sustaining life.
Roughly about 21% of air is oxygen.
The original name for oxygen was "dephlogisticated air." It was called this because it was believed to be air that had been purified by the removal of phlogiston, an outdated concept in chemistry.
A small percent . exhaled air always contains oxygen .
It had to. So yes in a way there always was oxygen. Because if there was no oxygen to would be just hydrogen in the air.
Oxygen, nitrogen, and various other gases are always present in the air. These gases are essential for supporting life on Earth.
It can supplement its oxygen by using oxygen from air as well as water.
when you inhale air into your lungs the concentration of oxygen in the blood can be no greater than that in the air.As the blood reaching the lungs is lower in oxygen there is transfer from the air to the blood stream until the concentrations stabilise.However there is no active transfer.Therefore there will always be Oxygen in exhaled air even if the initial oxygen concentration in the blood is zero as the air oxygen and the blood oxygen will reach a steady state equilibrium

It's the oxygen. Since oxygen doesn't dissolve into nitrogen - air is a mixture, not a solution - you can't call it the solute and the nitrogen the solvent, which may have been the answer you thought you were going to get.
there has always been air conditioning, just not in the condition i want it.
i think carbon reacts with oxygen in the air to burn things :?
Oxygen is in the air.

The oxygen content of air at any altitude is always about 21%
