Oxygen is the second most common/abundant gas in the air that we breathe. Nitrogen is the most abundant gas in the air we breathe. The composition of air is often treated as 79 mole or volume percent N2 and 21 mole or volume percent O2.
when you breathe out,the gas that is emitted is

We breathe in oxygen and we breathe out carbon dioxide
The colorless, odorless and tasteless gas that you breathe in is called oxygen, the chemical symbol of which is O2. Similarly, the gas that you breathe out is called carbon dioxide.
The same one you breathe in the most, Nitrogen.
This gas is argon - 0,9340 %.
Oxygen it helps the trees breathe too.
Plants breathe in a gas called carbon dioxide and then they breathe out the gas called oxygen which is what we breathe in!

Oxygen. You breathe out CO2
its nitrogen and is about 78% but the gas enter in our blood thourgh alveoli is oxygen.
