What is the chemical formula for the oxygen we breathe?

The chemical formula for the oxygen we breathe is O2.

What kind of oxygen do humans get from breathing?

Humans breathe in molecular oxygen (O2), which is essential for cellular respiration and is used by the body to produce energy. Oxygen is transported by the bloodstream to all the cells in the body to support various physiological processes.

How many percent of oxygen did you breathe?

What do humans breathe out and plants breathe in?

Carbon dioxide . It is part of the Carbon and Oxygen cycles. Humans ( all animals) breath in ( inhale) oxygen . It is used internally in the animated organism. It is then breathed out ( exhaled) as carbon dioxide. Carbon dioxide is a heavy gas, and 'falls' to the ground. Whereupon , it is absorbed by green plant life. Then under the process of photosynthesis within the plant , the carbon dioxide is broken down in to oxygen and carbon. The oxygen is released back into the atmosphere, and the carbon is kept in the plant as biomass.
