검증된 단계별 안내1
Recall the Law of Conservation of Mass, which states that mass cannot be created or destroyed in a chemical reaction.
Understand that matter is composed of atoms, which are the fundamental units of chemical elements.
Recognize that during a chemical reaction, atoms are rearranged to form new substances but are not destroyed or created.
Note that electrons and energy can be involved in reactions but are not the components whose mass is conserved in the same way atoms are.
Conclude that the component of matter that cannot be destroyed during a chemical reaction, according to the Law of Conservation of Mass, is the atom.
