Man in the constant search for knowledge, trying to understand and comprehend all the phenomena that may occur in the world, has created an endless number of Sciences and applications with which you were given gain knowledge about many thing and thus explain the by that of many phenomena that occur in life. I as well among so many sciences that has developed man, this article will include about chemistry, which in their field of study has allowed man to better understand the composition, structure and properties that possesses matter and so to understand more thoroughly the matter and forms and variations that may occur. Chemistry to study the characteristics presented in the matter, also performs analyses about changes that can present the matter due to chemical reactions that may occur and that likewise have caused changes in the composition and the form of matter. Chemistry in the development of the story, was best known as Alchemy and with the passage of time evolved to become in what is today the chemistry and the same concept was changed, leaving behind the designation of Alchemy. This change is due to the event in the history of the chemical revolution, which gave to the year of 1733. Chemistry to completed development of the study of matter, is to be split into several disciplines that carried out the analysis of the different types of materials, in such a way the chemistry and their different disciplines are grouped in depending on the kind of matter that is the subject of study, for the finar give a first individually and then general understanding of the characteristics and possible variations of the material through chemical reactions.
The different paliaciones with whom has chemistry, among the inorganic, which studied the inorganic matter; organic chemistry, as its object of study is the organic matter; Biochemistry, which deals with substances that occur in biological organisms; physical chemistry, which is about the energy aspects that arise in chemical systems, where the study can vary depending on the scale, which include the macroscopic, molecular and submolecular; analytical chemistry, that in the development of their field of study, analyzes different samples of matter, with the idea of being able to understand their composition and its structure. The previous applications of chemistry are more important and with further development, but are currently emerging new fields of action of chemistry, between which can highlight the neurochemistry, which studies aspects and chemical processes that occur in the brain. The importance of chemistry in the natural sciences, it is located as one of the basic sciences, because it is of great importance to many fields of knowledge, such as biology, medicine, the science of materials, geology, astronomy, among other areas of knowledge, since it allows to obtain some useful knowledge for these other sciences.
