There he equipped a fine laboratory, which attracted young chemists from all over Europe to learn about the “Chemical Revolution” then in progress.
Who did Antoine Lavoisier work with?
During the winter of 1782-83 he collaborated with his friend and mathematician Pierre-Simon de Lapace and published a paper in the Academy attacking phlogiston theory as “imaginary”, saying that it did not exist within metals or any other substance, and that the process of combustion and calcination of metals was …
What did Antoine Lavoisier do?
Antoine Lavoisier, a French chemist known as “the father of modern chemistry”, mainly discovered the role of oxygen in combustion and respiration, proved the law of conservation, reformed the chemical nomenclature, and named hydrogen.
What was Antoine Lavoisier’s contribution to the law of conservation of mass?
The Law of Conservation of Mass dates from Antoine Lavoisier’s 1789 discovery that mass is neither created nor destroyed in chemical reactions. In other words, the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction.

Who discovered work and energy?
James Prescott Joule
James Prescott Joule, (born December 24, 1818, Salford, Lancashire [now in Greater Manchester], England—died October 11, 1889, Sale, Cheshire), English physicist who established that the various forms of energy—mechanical, electrical, and heat—are basically the same and can be changed one into another.
Who discovered work energy theorem?
James Joule
W = Δ K E = 1 2 m v 2 2 − 1 2 m v 1 2 . The subscripts 2 and 1 indicate the final and initial velocity, respectively. This theorem was proposed and successfully tested by James Joule, shown in Figure 9.2.
