History Of Chemistry.
“Chemistry”. It is considered one of the natural sciences, which includes both physics, earth, astronomy and biology. This makes it a brilliant science among all sciences. They are a science concerned with studying the formation of matter and its various properties, and the various changes that take place at its level in case there are chemical reactions or changes in the energy level. Hence it is clear that all components of the universe are studied using this science. Human bodies, for example, are a chemical plant in which many reactions occur with every breath or movement, and these reactions enter into all fields of life such as food, clothing, and various means of transportation.
The history of chemistry cannot be linked to a specific time period. Development began from ancient times and continues to this day. Until 100 BC, civilizations used technology that eventually shaped the principles of chemistry. As I said before, it is a science in which a group of scientists has intertwined, but it has begun to separate from it. To be considered an independent science in itself with the beginning of the work of _”Antoine Lavoisier”_ who developed the law of conservation of the cluster, which states that the material in a closed system cannot be created or perished. Except that it can be rearranged. He also called for accurate measurement and quantitative observations on chemical phenomena. The history of chemistry is closely related to the history of thermodynamics, especially in the work of _”Jose Gibbs”._
Publicly studying chemistry is necessary to study some other sciences, especially medicine, pharmacy, biology, and engineering sciences, such as chemical engineering. Thus, we find that chemistry is divided into a group of basic branches:
is the study of the properties and interactions of inorganic compounds. There is no clear limit to the distinction between organic and inorganic chemistry, and there is a significant overlap between them, the most important of which is in another branch called the chemistry of organic metals.
is the study of the installation, properties, and reactions of organic compounds.
is the study of the physical origin of chemical reactions and systems. To further define it studies energy state changes in chemical reactions. Among the branches of interest to chemists specializing in thermochemistry, kinetic chemistry, quantum chemistry, statistical mechanics, spectra.
It is the study of chemicals and chemical reactions that occur in living organisms.
It is the analysis of samples of a substance to know its chemical composition and how to build it.
