9 Antoine Lavoisier

Daily 40 no. – 9 Antoine Lavoisier Daily 40 Hall of Fame! Congratulations to these writers! Antoine Lavoisier (1743 –1794) conducted experiments that prove respiration was basically a “slow combustion of organic material using inhaled oxygen.” His respiration experiments disproved the phlogiston theory. He also took Henry Cavendish’s “inflammable air”, named it hydrogen and combined it with oxygen which made water. --Karen Antoine Lavoiser’s enormous contributions to modern chemistry in eighteenth century France included the first law of conservation of mass, an essential factor in studying chemical reactions, and the naming of oxygen and hydrogen. His work also showed the inconsistencies of the phlogiston theory, which had prevented true understanding of combustion. --Madeline Born in 1743 Paris, Antoine Lavoisier theorized the law of conservation of mass, named oxygen and hydrogen, abolished the phlogiston theory, and constructed the metric system. Although he did not discover anything new, the explanations he provided for others’ discoveries were a great leap forward for the scientific community. --Dawy Antoine Laurent Lavoisier (1743-1794) was a French nobleman and chemist. He named oxygen and hydrogen, helped create the metric system, and wrote the first extensive list of elements. He also found out that, though matter may change its form, the mass always stays constant. --Alanna Antoine Lavoisier was a French chemist. He concluded that air must be made of two different gases, which he named oxygen and hydrogen. Lavoisier also concluded that combustion was a process where fuel combined with oxygen, disproving the phlogiston theory. His experiments also disproved Aristotle's air and fire elements. --Andrew 18th century French chemist Antoine Lavoisier, considered the “father of modern chemistry”, named the elements hydrogen and oxygen, disproved the phlogiston theory in his studies of combustion, stated the law of conservation of mass, and wrote Elementary Treatise on Chemistry, which is regarded as the first modern chemistry textbook. --Chantal The chemist Antoine Lavoisier lived from 1743-1794 in France. He discovered that air was made of at least Oxygen, Hydrogen, and Nitrogen, which he called Azote. Author of the Elementary Treatise on Chemistry, Lavoisier listed elements—such as phosphorous and nickel—and helped transition into the discovery of other elements. --Christine Antoine Lavoisier (1743-1794) is a French scientist who published the “Elementary Treatise on Chemistry”. He discovered and named oxygen and argued that there is no such a thing called phlogiston. He also believed in the “conservation of mass” and developed a proper definition for an element. --Dee Dee Antoine Lavoisier an 18th century French chemist was the first to discover that air was made up of oxygen and nitrogen. He had disproved the phlogiston theory and named the gas oxygen. He also wrote a chemical textbook, where the he wrote the first list of elements. --Denise Daily 40 no. – 9 Antoine Lavoisier Antoine Lavoisier, who lived from 1743 to 1794, named oxygen. He made the first chemistry textbook, which stated the law of conservation of mass which he discovered by carefully measuring reactants and products of experiments, showing scientists that materials in experiments must be carefully measured to get accurate results. --Eric Antoine Lavoisier was a French scientist who lived from 1743-1704 that finally proved that fire and water were NOT elements. He showed this by proving that air is a mixture. He showed that fire was not an element because it was a chemical reaction that gives off energy. --Eyad Antoine Laurent Lavoisier was born in 1743 in Paris. He is sometimes credited for recognizing and naming hydrogen and oxygen and abolished the phlogiston theory. He also helped build the metric system, created the first expansive list of elements, wrote Traité élémentaire de chemie and helped to correct chemical nomenclature. --Gennelle Antoine-Laurent de Lavoisier, a chemist, lived in France from 1743-1794. He corrected many misconceptions when he published Elementary Treatise on Chemistry. Lavoisier disproved the theory of phlogiston; he named Oxygen, Hydrogen, and helped identify Nitrogen but named it Azote. In addition, he discovered the conservation of mass principle. --Isaac Antoine Laurent de Lavoisier(1743-1974) was a French chemist. He discovered that when matter changes shape, its mass is the same. He was called the “father of modern chemistry” because he named oxygen and hydrogen, disproved phlogiston theory, started developing the metric system, and wrote the first comprehensive list of elements. --Jaya Antoine Lavoisier (1743 – 1794) was a French chemist. His lasting contributions to chemistry include naming Oxygen and Hydrogen, starting the periodic table by making a list, and developing the law of conservation of mass, which states that mass is not destroyed nor created in reactions. --Jeff Lavoisier, a French chemist, was born in Paris on August 26, 1743. He disproved the phlogiston theory by proving the law of conservation. He also discovered that diamond is a crystalline form of carbon. He did not discover any elements. He was beheaded during the French Revolution. --Julia Antoine Lavoisier studied chemistry in France from 1743 to 1794. He made important contributions to the periodic table of elements by disproving the ‘phlogiston’ theory, recognizing oxygen as an element. He also discovered hydrogen. He compiled the first list of the known elements at the time. --Katy The French scientist Antoine Lavoisier’s most notable contribution to science was probably his support of thorough experimental evidence. Also of note was his discovery of the role that oxygen plays in combustion and respiration. He proved that the Phlogiston theory was false. --Oliver Britishman Antoine Lavoisier lived from 1743–1794. Lavoisier heated mercury and air for 12 days. Red mercury calx formed and the volume of the air had decreased from 50 to 42in3. The calx was then heated and 8in3 oxygen was produced proving that phlogiston was not produced by heating. --Tatiana Daily 40 no. – 9 Antoine Lavoisier French chemist Antoine Lavoisier contributed a great deal to chemistry. He clarified Priestly’s idea of phlogiston, recognizing the elements that made water. He also experimented with oxygen and discovered its presence within animal and plant respiration. More importantly, Lavoisier was responsible for compiling the elements on the periodic table. --Tokunbo In respect to science Antoine Lavoisier (a French nobleman) wrote numerous books such as Méthode de nomenclature chimiquein in which he reformed chemical nomenclature, discussed the law of conservation of mass, isolated oxygen and hydrogen, abolished the phlogiston theory, contributed to the metric system, and wrote a list of elements. --Victoria Antoine Lavoisier, lived from August 26, 1743- May 8, 1794 in France. He concluded that hydrogen and oxygen made up air, and in doing so proved that water was not an element. He also named oxygen. However, Lavoisier was more of a theorist, and did not discover any elements. --Yulan .
