The headline of the text is "Chemistry". The text informs on what is chemistry. The author dwells upon definitions of this science. He mentions the most popular dictionary definition in his article. The author writes: chemistry is a science of the composition, structure properties, and reactions of matter, especially of atomic and molecular systems. He is sure that this definition is not the only one and gives another. Chemistry is a science dealing with the compositions of matter and the changes in composition that matter undergoes. At the beginning the storyteller makes close study of chemistry's origin and relationship of chemistry with other sciences. He have no doubt that chemistry closely related to biology, because life itself is an essentially complicated system of interrelated chemical processes. The author considers that chemistry's origin goes back to ancient times. Then much attention is given to emergence of modern chemistry. It would be wise to mentoin here that modern chemistry began with the work of Robert Boyle, who studied quantitatively the relationship between the volume of a gas and the external pressure upon it. This text also tells about many great scientists,which devoted their life to the development of chemistry. The examples referred in this article illustrate well enough. The author emphasizes Bohr's theory of the hydrogen atom,Kekule's and Butlerov's structural theory of organic chemistry. Mendeleyev's discovery of regularities in the properties of the elements is the main fact in this text.
To sum up it should be noted that chemistry is a science of future. It will be possible tocreat many new goods, plastics,polymers.
