Responses
The mass of the substance changes.
The mass of the substance changes.
The appearance of a substance changes, but it is still the same substance.
The appearance of a substance changes, but it is still the same substance.
The state of the substance changes.
The state of the substance changes.
Atoms of one or more substances rearrange into a new substance.
Atoms of one or more substances rearrange into a new substance.
Atoms of one or more substances rearrange into a new substance.
The correct answer is: Atoms of one or more substances rearrange into a new substance.
During a chemical change, the atoms in one or more substances rearrange to form new substances with different properties. This rearrangement results in the formation of completely new chemical compounds. This process is not reversible through physical means and leads to the creation of different substances altogether.
On the other hand, physical changes do not involve a rearrangement of atoms. Physical changes only alter the appearance or state of a substance without changing its chemical composition. This means that physical changes do not lead to the formation of new substances and the atoms remain the same.
To determine the answer to this question, one can understand the difference between chemical and physical changes. Chemical changes involve the rearrangement of atoms, while physical changes only impact the physical properties of a substance. By recognizing the nature of the changes described in the options, it becomes clear that only the rearrangement of atoms into new substances is characteristic of a chemical change.
