Lavoisier developed a new theory of combustion that overturned the phlogiston theory. What measurements were central to his theory, and what key discovery did he make?

Lavoiser proposed a theory in charge of writing the combustion correctly, denying the phlogiston.

Lavoiser said that combustion is carried out in a medium where there is oxygen, giving as a product water and carbon dioxide.

This combustion results in the decrease in the volume of the material that burns.

Furthermore lavoiser discovered the importance of oxygen in animal respiration.

Explanation:

Lavoisier argued that if or if the presence of oxygen must be present, it is an irreversible and spontaneous process.
