He used the Combustion theory as the starting point for this idea, which would eventually lead to the development of the atomic theory. He also discovered hydrogen; Refuted the phlogiston theory; Explained the combustion and breathing In terms of chemical reactions involving oxygen. For example, he believed that acidity was caused by the presence of oxygen in a compound. DEATH OF LAVOISIER by John H. Lienhard.

He proposed that it was necessary to distinguish fact from fiction when conducting experiments or offering a hypothesis. Today, we destroy suddenly what we've built slowly.
