The science which scrutinizes substance is called chemistry. The alchemists are known as the first chemists. They attempted to create the elixir of life and manage to turn iron ore into gold. The primary objective of the today's chemists is to study the reactions that are happening on the molecular level and get known more about the processes occur between various matters. It is also quite important to detect the laws to have the possibility to create the required matters from other ones. Chemistry, biology and physics are the studies that have got lots of joint objectives.

Chemistry has the huge amount of different subdivisions.

Organic chemistry is named organic due to it was believed that organic compounds had a lot to do with life. Nevertheless, this was a misunderstanding. Organic components may be developed in ways that do not involve life or living objects. Simultaneously, many inorganic components are necessary to life, for example copper or iron.

The matters that comprise carbon and hydrogen are the main objects of researches provided by organic chemistry. This science studies their structure, features, composition and reactions. Organic combinations are commonly used in a variety of products, including plastics, foods, drugs, etc.

Analytical chemistry studies composition of organic and inorganic matters. The molecules and atoms of the substance are examined in details by that science. It studies the components given, their composition and properties. Analytical and physical chemistry are quite similar, because they study the same reactions but gain some different information from them. It is based on the researches and the results are quite useful for providing the defense of the environmental and saving some natural resources.
