hel please help like really give me an example of a process that obeys the law of conservation of mass that u use everyday or notice and explain how it works answer hellp

This is the best example I could find:

“The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. For example, when wood burns, the mass of the soot, ashes, and gases, equals the original mass of the charcoal and the oxygen when it first reacted.”

Here is the link to the website if you need more information:

Noble gases is far right
