Antoine Lavoisier (1743-1794) <br />
<div style="text-align: justify;">French chemist who, through a conscious revolution, became the father of modern chemistry. As a student, he stated "I am young and avid for glory." He was educated in a radical tradition, a friend of Condillac and read Maquois's dictionary. He won a prize on lighting the streets of Paris, and designed a new method for preparing saltpeter. He also married a young, beautiful 13-year-old girl named Marie-Anne, who translated from English for him and illustrated his books. Lavoisier demonstrated with careful measurements that transmutation of water to earth was not possible, but that the sediment observed from boiling water came from the container. He burnt phosphorus and sulfur in air, and proved that the products weighed more than he original. Nevertheless, the weight gained was lost from the air. Thus he established the Law of Conservation of Mass. </div><div style="text-align: justify;">Repeating the experiments of Priestley he demonstrated that air is composed of two parts, one of which combines with metals to form calxes. However, he tried to take credit for Priestley's discovery. This tendency to use the results of others without acknowledgment then draw conclusions was characteristic of Lavoisier. In <i>Considérations Générales sur la Nature des Acides</i> (1778), he demonstrated that the "air" responsible for combustion was also the source of acidity. The next year, he named this portion oxygen (Greek for acid-former), and the other azote (Greek for no life). He also discovered that the inflammable air of Cavendish which he termed hydrogen (Greek for water-former), combined with oxygen to produce a dew, as Priestley had reported, which appeared to be water. </div><div style="text-align: justify;">In <i>Reflexions sur le Phlogistique</i> (1783), Lavoisier showed the phlogiston theory to be inconsistent. In <i>Methods of Chemical Nomenclature</i> (1787), he invented the system of chemical nomenclature still largely in use today, including names such as sulfuric acid, sulfates, and sulfites. His <i>Traité Élémentaire de Chimie (Elementary Treatise of Chemistry,</i> 1789) was the first modern chemical textbook, and presented a unified view of new theories of chemistry, contained a clear statement of the Law of Conservation of Mass, and denied the existence of phlogiston. In addition, it contained a list of elements, or substances that could not be broken down further, which included oxygen, nitrogen, hydrogen, phosphorus, mercury, zinc, and sulfur. His list, however, also included light, <img alt="Eric Weisstein's World of Physics" height="12" src="http://scienceworld.wolfram.com/images/crossrefs/physics.gif" width="12" /> and caloric, <img alt="Eric Weisstein's World of Physics" height="12" src="http://scienceworld.wolfram.com/images/crossrefs/physics.gif" width="12" /> which he believed to be material substances. In the work, Lavoisier underscored the observational basis of his chemistry, stating "I have tried...to arrive at the truth by linking up facts; to suppress as much as possible the use of reasoning, which is often an unreliable instrument which deceives us, in order to follow as much as possible the torch of observation and of experiment." Nevertheless, he believed that the real existence of atoms was philosophically impossible. Lavoisier demonstrated that organisms disassemble and reconstitute atmospheric air in the same manner as a burning body. </div><div style="text-align: justify;">With Laplace, used a calorimeter to estimate the heat evolved per unit of carbon dioxide produced. They found the same ratio for a flame and animals, indicating that animals produced energy by a type of combustion. Lavoisier believed in the radical theory, believing that radicals, which function as a single group in a chemical reaction, would combine with oxygen in reactions. He believed all acids contained oxygen. He also discovered that diamond is a crystalline form of carbon. Lavoisier made many fundamental contributions to the science of chemistry. The revolution in chemistry which he brought about was a result of a conscious effort to fit all experiments into the framework of a single theory. He established the consistent use of chemical balance, used oxygen to overthrow the phlogiston theory, and developed a new system of chemical nomenclature. He was beheaded during the French revolution.</div>Tania and Carloshttp://www.blogger.com/profile/14586363919511365105noreply@blogger.com0tag:blogger.com,1999:blog-5228042921095741126.post-33950759693545695962011-01-21T08:09:00.000-08:002011-01-21T08:09:48.693-08:00Memo<div style="text-align: justify;"><link href="file:///C:%5CDOCUME%7E1%5CAlum-01%5CCONFIG%7E1%5CTemp%5Cmsohtml1%5C02%5Cclip_filelist.xml" rel="File-List"></link><style>
