Chemistry is a quite old science that studies different types of substances. The alchemists are considered to be the first chemists. They attempted to create the elixir of life and manage to transform iron ore into gold. The primary objective of the modern chemists is to study the processes that are happening on the atomic level and get known more about the processes happen between different matters. Another purpose of this modern science is to find the laws that may explain the processes and phenomena in chemical reactions. It can assist to generate the needed matters artificially. To execute the chemical experiments, that is essential to be good in physics and biology.

This science is divided into inorganic chemistry, organic chemistry, analytical chemistry, biochemistry, physical chemistry and lots of other more narrow spheres.

The calling of organic chemistry has been proposed because chemists thought that the organic elements have the connection to the life. Nevertheless, this was a misunderstanding. Organic components may be produced in ways which do not involve life or living organisms. On the contrary, lots of inorganic components are necessary for some life processes, for instance, cooper and iron.

Organic chemistry performs the analysis of matters which are made of carbon and hydrogen. Thanks to it year by year the humanity get known more and more about it and this knowledge is very helpful. There are lots of commonly utilized products that couldn't be invented without the researches of organic chemistry.

Analytical chemistry studies combinations of organic and inorganic matters. The molecules and atoms of the substance are examined in details by that science. It researches the elements given, their composition and properties. Analytical and physical chemistry are quite similar, due to they study the similar reactions but gain some different information from them. As is aimed on experiment and stable facts, its finding are useful for biomedical or environmental monitoring.
