What was Antoine Laurent lavoisier's experience?

Born in Paris, Antoine Laurent lavoisier is a famous French chemist and one of the founders of modern chemistry. 1743 was born in Paris on August 26th, and 1794 died in the same place on May 8th. 1763 obtained French bachelor's degree and lawyer's practice certificate, and then switched to natural science research. His earliest chemical paper was published in the Journal of Paris Academy of Sciences in 1768, which was about gypsum. In his paper, he pointed out that gypsum is a compound formed by sulfuric acid and lime, which releases water vapor when heated. 1765 Elected alternate academician of Paris Academy of Sciences. 1768, he successfully developed a floating and sinking instrument, which can be used to analyze mineral water. From 65438 to 0775, he was the director of the Royal Gunpowder Bureau, which had a very good laboratory in which lavoisier did a lot of research. 65438-0778 Professor of Royal Academy of Sciences. 1774 10, Priest introduced his own experiment to lavoisier: when mercury oxide is heated, dephosphorization gas can be obtained, which can make the candle burn brighter and help to breathe. Lavoisier repeated priestley's experiment and got the same result. But lavoisier didn't believe in phlogiston, so he thought this gas was an element. 1777, he officially named this gas oxygen, which means acidic element. In 1777, lavoisier submitted a report "Introduction to Combustion" to the Paris Academy of Sciences through metal calcination experiments, which expounded the oxidation theory of combustion. The key points are as follows: (1) Light and heat are released during combustion; (2) Only in the presence of oxygen can a substance burn; (3) Air consists of two components. When a substance burns in the air, it absorbs the oxygen in the air, so its weight increases, and the added weight of the substance is exactly the weight of the oxygen it absorbs; (4) Generally combustible substances (nonmetals) usually turn into acids after burning, and oxygen is the origin of acids, and all acids contain oxygen. The metal becomes calcined ash after calcination. They are metal oxides. He also proved through accurate quantitative experiments that although the state of substances has changed in a series of chemical reactions, the total amount of substances involved in the reaction has not changed before and after the reaction. Lavoisier proved the law of conservation of mass in chemical reaction through experiments. Lavoisier's oxidation theory completely overthrew the phlogiston theory, turned a new page in the history of chemistry, and made chemistry flourish.
