I suppose one should ask WHICH experiment by Lavoisier but I agree with your answer.

i kind of agree

which of the following is a chemical change?

Yeet i think d cause same in mine

Your answer is correct! Antoine Lavoisier's experiments demonstrated that mass is neither lost nor gained during a chemical change. Lavoisier is known as the Father of Modern Chemistry and is credited with establishing the law of conservation of mass. This law states that in a closed system, the total mass of the substances present before a chemical reaction is equal to the total mass after the reaction. Lavoisier's experiments involved carefully measuring the mass of reactants and products and finding that the total mass remained constant. This was a groundbreaking observation that helped shape the understanding of chemical reactions and laid the foundation for modern chemistry.
