Question

state the law of conservation of matter​

Answer 1

Answer:

The law of conservation of mass or principle of mass conservation states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as the system's mass cannot change, so quantity can neither be added nor be removed.

Explanation:

chemical reaction, the total mass of the products is equal to the total mass of the reactants . ... The sum of the relative formula masses of the reactants is equal to the sum of the relative formula masses of the products.

Answer 2

The law of conservation of mass or principle of mass conservation states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as the system's mass cannot change, so quantity can neither be added nor be removed. Therefore, the quantity of mass is conserved over time.
