Antoine Lavoisier Trivia Questions

His law says mass is neither created nor destroyed in a chemical reaction—it is conserved. This was a revolutionary principle for 18th-century chemistry.

He was a member of the hated Ferme Générale tax farm. The revolutionary tribunal sentenced him to the guillotine in 1794, despite his scientific fame.

In 1783, he and Laplace synthesized water from hydrogen and oxygen, disproving the ancient idea that water was a fundamental element.

He did propose the caloric theory, but later experiments on heat and friction by Rumford and others disproved it. Lavoisier died before these findings emerged.

Priestley actually isolated oxygen first in 1774, but Lavoisier correctly identified it as a distinct element and named it, explaining combustion without phlogiston.

Lavoisier coined the name 'oxygen' from Greek for 'acid-former' and 'hydrogen' from 'water-former', replacing earlier terms like 'phlogiston'.

Balances were used earlier by alchemists and scientists like Robert Boyle. Lavoisier’s innovation was systematically applying precise measurements to track mass changes in reactions.

Marie-Anne Paulze Lavoisier was a crucial collaborator, translating English works (like Priestley’s) into French and creating detailed engravings of experiments.
