A
Creation or destruction of atoms
B
Change in physical state
C
Change in the identity of atoms
D
Formation of new substances
Verified step by step guidance1
Understand the Law of Conservation of Mass, which states that atoms cannot be created or destroyed in a chemical reaction; they are only rearranged.
Recognize that a change in physical state (such as solid to liquid) is a physical change and can occur during or alongside chemical reactions.
Know that a change in the identity of atoms means atoms are transformed into different elements, which does not happen in ordinary chemical reactions but rather in nuclear reactions.
Identify that the formation of new substances is a hallmark of chemical reactions, where atoms are rearranged to form different compounds.
Conclude that the creation or destruction of atoms cannot take place during a chemical reaction because it violates the conservation of atoms.
