Question

The scales shown in the introduction measure mass, or the amount of matter in a particular object. The scientific law of conservation of mass states that matter cannot be created or destroyed during a chemical reaction, but it can change from one form to another. Did the simulation support this scientific law? Explain why or why not.

Answer 1

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 system's mass cannot change, so quantity can neither be added nor be removed. Hence, the quantity of mass is conserved over time.

Answer 2

Answer:

Yes, it did.

Explanation:

Both the scales and the graph in the introduction showed that the mass of the products and the reactants were equal, even though the forms of the molecules changed. In the simulation, atoms and molecules formed new molecules during the chemical reactions, but the number of each type of atom stayed the same.
