Lavoisier in his youth Lavoisiers education was filled with the ideals of the French Enlightenment, and he felt fascination for Maquois' dictionary. His devotion and passion for chemistry was also influenced by tienne Condillac, a prominent French scholar of the eighteenth century. Beginning at the age of 11, Lavoisier attended the College Mazarin from 1754 to 1761, studying under the famed astronomer and mathematician, the Abbe La Caille, who had measured an arc of the meridian at the Cape of Good Hope. Marie translated documents from English for him, including Richard Kirwan's " Essay on Phlogiston " and Joseph Priestley 's research. She created many sketches and carved engravings of the laboratory instruments used by Lavoisier and his colleagues.
It was only after the realization that matter can be neither created nor destroyed within a physical system that chemistry became an exact science. Major works in analytical chemistry and chemical nomenclature A replica of Lavoisier's laboratory at the Deutsches Museum in Munich, Germany Lavoisier.

Sulfur, when burning, absorbs oxygen gas; the resulting acid is considerably heavier than the sulfur burned; its weight is equal to the sum of weights of the sulfur burned and the oxygen absorbed. This result astonished many people, because at that time everyone knew that water was itself one of the indivisible elements. Hydrogen means water former in Greek. It required 85 parts by weight of oxygen and 15 parts of hydrogen to compose 100 parts of water. He was able to determine the exact proportions of the element oxygen in the air by weighing and measuring the solids and gasses involved both before and after the experiments. Research on hydrogen and his role in disproving the phlogiston theory Apparatus for hydrogen combustion. Beginning at the age of 11, Lavoisier attended the College Mazarin from 1754 to 1761, studying under the famed astronomer and mathematician, the Abbe La Caille, who had measured an arc of the meridian at the Cape of Good Hope. In 1783 his paper Reflections on Phlogiston marked the beginning of the end for phlogiston and a triumph for Lavoisiers oxygen theory and quantitative chemistry. Lavoisiers list of elements In 1789 Lavoisier published his groundbreaking Elementary Treatise on Chemistry. 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 sulphur. This list forms the basis for the modern periodic table of the elements. He also included a substance called caloric, which was later shown, like phlogiston, to be fictitious. In fact, so much of Elementary Treatise on Chemistry involves caloric in explanations that it slightly spoils the work. Also, Lavoisier clarified the concept of an element as a simple substance that could not be broken down by any known method of chemical analysis, and he devised a theory of the formation of chemical compounds from elements. While this may seem obvious to us today, it was less so in those days (hence the general support for the phlogiston theory). After carrying out work with a number of different substances, and recalling earlier work such as his work in 1772 with carbon. Burr, on the other hand fired with deadly aim, and his bullet found its mark. The bullet struck Hamilton in the chest and lodged in his spine. The injured Hamilton was taken to the Greenwich Village home of a friend where doctors tried in vain.

They had inconsistent, confused theories, chief of which was the theory of phlogiston, an undetectable substance which sometimes had negative mass! We now know that combustion happens when substances react with oxygen at high temperatures.
