Lavoisier's work revolutionized and reformed the world of chemistry. He changed the world of chemistry from qualitative to quantitative, using precise measurements in his experiments. His experiments changed the views and concepts involved in chemistry. Even though his work sometimes got criticism from society, the world of chemistry would be very different today if it weren't for him.

He defined elements and showed that Aristotle's four elements were incorrect. He showed that fire was not even a substance, atmospheric air was a mixture of oxygen and nitrogen, and that water is a compound of hydrogen and oxygen. He created a new method of defining elements and classifying them. His work on respiration showed the role of oxygen and carbon dioxide (fixed air) in nature and life. Proving the Phlogiston Theory false and creating his Theory of Combustion showed how oxygen had a role in combustion, not phlogiston.

He wrote Elementary Treatise of Chemistry which became the first modern chemical textbook and presented a unified view of chemistry. Some of the concepts presented in his book are still used by modern chemists. His book included elements: oxygen, nitrogen, hydrogen, phosphorus, mercury, zinc, and sulfur, which set a path for people finding more elements.

Lavoisier's experiments and conclusion have revolutionized and reformed the world of chemistry and its effect is still felt today.
