Answer 1

Atoms rearrange to form new substances

Step-by-step explanation:

Answer 2

Answer: Option (B) is the correct answer.

Step-by-step explanation:

A change which brings change in composition of atoms of a substance to result in the formation of new substances is known as a chemical change.

Therefore, in a chemical change new substances are formed which have different properties as compared to their reactants.

For example,
`2Na + Cl_(2) \rightarrow 2NaCl`

Thus, we can conclude that during all chemical changes atoms rearrange to form new substances.
