Some facts about chemistry

The science of chemistry deals with substances. Chemistry is the investigation and discussion of the properties of substances.

Common examples of substances are: water, sugar, salt, copper, iron and many others. Chemists study substances in order to learn as much as they can about their properties and about their reactions that change them into other substances. This knowledge is very important as it can make the world a better place to live in, it can make people happier, and it can raise their standard of living.

Chemist discovered many laws, investigated many important phenomena in life. They produced many artificial substances which have valuable properties. Chemistry has two main aspects: descriptive chemistry, the discovery of chemical facts, and theoretical chemistry, the formulation of theories.

The broad field of chemistry may also be divided in other ways. An important division of chemistry is that into the branches of organic chemistry and inorganic chemistry. Organic chemistry is the chemistry of the compounds of carbon that occur in plants and animals. Inorganic chemistry is the chemistry of the compounds of elements other than carbon. Each of these branches of chemistry is in a part descriptive and in part theoretical.

Chemistry plays an important role in the development of other sciences such as physics, biochemistry, geology and a lot of others sciences. The famous chemists are: N. Kurnakov, N. Zelinsky, A. Favorsky, A. Arbuzov, A. Butlerov, N. Semenov.
