The Law of Conservation of Matter (matter and mass are essentially the same).
Explanation:
According to law of conservation of matter, matter is neither created nor destroyed. It can only be transformed from one form to another.
For example, [tex]C + O_{2} \rightarrow CO_{2}[/tex]
This chemical reaction equation shows that carbon atom and oxygen atom when combined together results into the formation of new matter that is, carbon dioxide.
Thus, we can conclude that in any ordinary chemical reaction, matter is neither created nor destroyed; it is simply changed from one chemical substance to another. This principle is called the Law of conservation of matter.
