He combined elements such as iron and copper with oxygen, based off the reaction he found that oxygen's composition was always one of two.

What was Antoine Lavoisier important discovery?
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.Joseph Proust is credited with the discovery of the Law of definite proportions.
What laws provided evidence for the existence of atoms?
The law of definite proportions, the law of conservation of mass, and the law of multiple proportions all provide evidence for the existence of atoms.
Is it true that a chemical has a definite composition?
Yes, after the Law of definite proportions; but now it is clear that this law is not applicable to all known chemical compounds.
Does The Law of Definite Proportions state that substances combine in predictable proportions and that excess reactants remain unchanged?
Yes, it is true; but today this law is not generally valid.
