What fact does Antoine Lavoisier's work show? A. the overall volume before a reaction is equal to the overall volume after a rea
ction. B. the overall mass before a reaction is equal to the overall mass after a reaction. C. the overall thermal energy before a reaction is equal to the overall thermal energy after a reaction. D. the overall temperature before a reaction is equal to the overall temperature after a reaction.
The correct answer is B. Antoine-Laurent de Lavoisier was a French chemist, biologist and economist who discovered <em>the law of conservation of matter</em> in 1785.
This law states that during a chemical reaction, <u>the total mass in the system remains constant</u>, that is, the mass consumed of the reactants is equal to the mass of the products obtained.
