The air we breathe is a complex mixture of chemical compounds and air molecules. The air we breathe contains different molecules of oxygen and nitrogen, and different molecules of carbon and hydrogen. Each molecule has its own specific properties, and each one of these properties has its own specific characteristics. The air we breathe is a complex mixture of chemical compounds and air molecules.
