Antoine-Laurent de Lavoisier (/ l ə ˈ v w ɑː z i eɪ / lə-VWAH-zee-ay; [1] [2] [3] French: [ɑ̃twan lɔʁɑ̃ də lavwazje]; 26 August 1743 – 8 May 1794), [4] also Antoine Lavoisier after the French Revolution, was a French nobleman and chemist who was central to the 18th-century chemical revolution and who had a large influence on both the history of chemistry and the history of biology.
Russian scientist Mikhail Lomonosov formulated the law of mass conservation in 1756 and came to the conclusion that the phlogiston theory is incorrect. [3] [4] [5] Antoine Lavoisier's discovery of the law of conservation of mass led to many new findings in the 19th century.
Mikhail Vasilyevich Lomonosov (/ ˌ l ɒ m ə ˈ n ɒ s ɒ f /; [1] Russian: Михаил Васильевич Ломоносов, IPA: [mʲɪxɐˈil vɐˈsʲilʲjɪvʲɪtɕ ləmɐˈnosəf] ⓘ; 19 November [O.S. 8 November] 1711 – 15 April [O.S. 4 April] 1765) was a Russian polymath, scientist and writer, who made important contributions to literature, education, and science.
The use of closed vessels by Lavoisier and earlier by the Russian scientist Mikhail Lomonosov also negated the buoyancy that had disguised the weight of the gases of combustion, and culminated in the principle of mass conservation. These observations solved the mass paradox and set the stage for the new oxygen theory of combustion. [20]
1756: Law of conservation of matter – discovered by Mikhail Lomonosov, 1756; [28] and independently by Antoine Lavoisier, 1778. [29] 1773: Oxygen – Carl Wilhelm Scheele (Uppsala, 1773), Joseph Priestley (Wiltshire, 1774). The term was coined by Antoine Lavoisier (1777).

During the 19th and 20th century, this transformation was credited to the work of the French chemist Antoine Lavoisier (the "father of modern chemistry"). [2] However, recent work on the history of early modern chemistry considers the chemical revolution to consist of gradual changes in chemical theory and practice that emerged over a period of ...
Antoine-Laurent de 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 the original samples, with the mass gained being lost from the ...
