If the total mass in a closed container after a chemical reaction remains equal to the total mass before the reaction, which law does this illustrate?
Answer and explanation
Correct answer: Law of conservation of mass
In a closed container, no matter enters or leaves. During a chemical reaction, atoms are only rearranged; they are neither created nor destroyed. Therefore, the total mass before and after the reaction remains the same. This is the law of conservation of mass, whereas the law of reflection concerns the reflection of light.
