What does the law of conservation of matter or the law of conservation of mass tell the students

Answer 1

The law of conservation of matter (or the law of conservation of mass) tells students that matter cannot be created or destroyed in a chemical reaction. It states that the total mass (or total amount) of substances in a closed system before a chemical reaction must equal the total mass (or total amount) of substances in the system after the reaction. In simpler terms, it means that atoms are neither created nor destroyed during a chemical reaction, but instead rearranged to form new substances. This concept is important for understanding the balanced equations in chemical reactions and the concept of stoichiometry.
