What does the law of conservation of matter (or the law of conservation of mass) tell the students
Matter might be lost in a chemical or physical process
Matter might be gained in a chemical or physical process
Matter is always gained or lost in a chemical or physical process
Matter is never gained or lost in a chemical or physical process
The law of conservation of matter (or the law of conservation of mass) tells the students that matter is never gained or lost in a chemical or physical process.
The law of conservation of matter, also known as the law of conservation of mass, states that matter is never gained or lost in a chemical or physical process. This means that the total mass of the substances involved in a reaction remains constant before and after the process. The atoms are rearranged or combined in different ways, but no matter is created or destroyed. Therefore, options A, B, and C are incorrect, while option D is the correct statement.
