Question

What does the law of conversation of mass state

Answer 1

The law of conservation of mass states that in a closed system, the total mass of a substance remains constant over time, regardless of the processes that occur within the system. This principle, first formulated by Antoine Lavoisier in the 18th century, implies that matter cannot be created or destroyed; it can only change forms or be rearranged during chemical reactions or physical changes. Therefore, the mass of the reactants in a chemical reaction will always equal the mass of the products.
