Abstract
This document provides a detailed analysis of the composition of air and the role of oxygen molecules in the human body. It discusses the differences in air composition between inhaled and exhaled air, and the production of carbon dioxide as a byproduct of muscle activity. The document also explains the concept of mixtures and pure bodies at the molecular level.

[...] composition of the air be correct. As previously mentioned, 80% 2 molecules 20% Exercise 2 In the erlenmeyer there are molecules of sulfur dioxide and molecules of oxygen. It is therefore a mixture. In the balloon there are only molecules of oxygen. It is therefore a pure body. In the flask there are only molecules of carbon dioxide. It is therefore a pure body. We can talk about the water molecule because water is a pure body. It is not a mixture. [...]
[...] Exercise 3 The gas consumed by the organism is oxygen. In fact, the exhaled air contains less oxygen (16.57%) than the inhaled air (20.94%). Therefore, oxygen has been consumed in the organism. The gas produced by the organism is carbon dioxide. In fact, the exhaled air contains more carbon dioxide (4.46%) than the inhaled air (0.03%). Therefore, carbon dioxide has been produced in the organism. The gas necessary for life is oxygen. Indeed, it is the one that is transported from the lungs to the muscles, by the blood, to make the muscles work. [...]
