The science which studies substance is called chemistry. It was born out of alchemy, an ancient science that sought, among other objectives, to find the elixir of life and do gold from iron. Today chemistry just scrutinizes the components of different substances, their molecular structure and the processes which happen while various substances are being combined. Another purpose of that newest science is to determine the laws which can explain the relations and phenomena in chemical reactions. That can help to generate the needed substances artificially. Chemistry cooperates quite closely with biology and physics.
This science is subdivided into inorganic chemistry, organic chemistry, analytical chemistry, biochemistry, physical chemistry and some other more specific spheres.
The calling of organic chemistry has been created because scientists believed that the organic components have the connection to the life. But today's science has proved that not all the elements of organic chemistry are connected to the life and living objects. Simultaneously, lots of inorganic elements are essential to life, for example copper or iron.
Organic chemistry deals primarily with chemical compounds which are made of carbon and hydrogen. Thanks to it year by year the humankind get known more and more about it and this knowledge is quite useful. Organic combinations are widely utilized in a variety of goods, including plastics, foods, drugs, etc.
Analytical chemistry is a subdivision of chemistry that tries to determine the laws of reactions which occur in combinations of organic and inorganic matters. It defines the geometric structure of molecules that assists to understand the reactions better. It researches the elements given, their composition and features. Analytical chemistry is experimental in nature and in that way it is similar to physical chemistry. It is based on the researches and the results are very useful for providing the safety of the environmental and saving the natural resources.
