Abstract
Chemistry is the science that studies the composition, structure and properties of matter, as well as the transformations that it can undergo. It is at the heart of understanding many aspects of nature and life. The size of the compounds studied in chemistry varies from reactions between simple atoms to molecular structures of several tens of thousands of atoms (DNA, proteins, crystals, etc.). Studying the world at the molecular level allows us to better understand the world at the human level. Indeed, chemistry is part of everyday life. Using light, plants produce the nutrients they need by capturing gases dissolved in the air (mostly nitrogen) and drawing water and mineral salts from the soil. They do chemistry. When we heat food, when we cook an egg, pasta, etc. We also do chemistry. All beauty products, perfumes and creams have a chemical origin. They are created or synthesized from atoms and molecules that react with each other. Either by imitating and reproducing what happens in nature, or by creating new compounds.
