lavoisier Chemistry is the science in charge of studying the composition, structure and properties of matter, as well as the changes that occur in it during chemical reactions. His field of study extends from atoms and molecules to complex aggregates of matter such as crystals, colloids …….

Given the great breadth of this science, it has been divided into disciplines that study different types of matter: Organic Chemistry, Inorganic Chemistry, Physical Chemistry, Analytical Chemistry, Nuclear Chemistry, Chemistry of Materials and Biochemistry. Many other disciplines have emerged over the years to apply chemical knowledge to highly specialized fields, such as: Atmospheric chemistry, Chemical engineering, Electrochemistry, Environmental chemistry, Geochemistry, Materials science, Molecular biology, Nanotechnology, Chemistry Organometallic, Polymer Chemistry, Solid State Chemistry, Supramolecular Chemistry, Solid State Chemistry, Thermochemistry……

To give an idea of the importance that chemistry has today, I will give as data the production of the chemical industry in 2004. The 50 most important chemical companies in the world had a turnover of 587 billion dollars.
