What did scientist Antoine Lavoisier discover?

Answer 1

He discovered that the phlogiston theory was incorrect, and recognized and named oxygen and hydrogen. He accepted that sulfur is an element, had contributions to metric system, established a list of chemical elements, discovered that diamond is a form of carbon, discovered that water is formed from oxygen and hydrogen, etc.

He proposed independently (he had any knowledge of Lomonosov works) the law of mass conservation.

Answer 2

Lavoisier's principle is that within a "closed system", the mass of substances within that system cannot change. It is known also as the mass conservation law. It is most often applied in reference to chemical reactions where the combined mass of the reactants used is equal to the mass of the resulting compound.

Answer 3

Antoine-Laurent de Lavoisier (August 1743 to May 1794) was a French nobleman and chemist in the 18th-century Chemical Revolution. Lavoisier discovered the role that oxygen plays in combustion after he recognized and named oxygen and hydrogen.

Answer 4

he proved that when metal is heated it turns into a compond

Answer 5

Antoine Laurent Lavoisier discovered the phlogiston theory but abolished it because he figured out it wasn't right.

Answer 6

He discovered that,although matter may change its form or shape,its mass always remains the same.

Answer 7

Antoine Lavoisier discovered the role of oxygen in combustion and formulated the law of conservation of mass. He also helped to develop the modern system of chemical nomenclature.
