Answer:
The correct option is 3. No, because atoms are not rearranged to create new substances.
Explanation:
A chemical reaction can be described as a reaction in which reactants combine to form new products. For example, the burning of wood is a chemical reaction.
A physical reaction can be described as the one in which no new products are made. The state of a substance might change from one form to another but no new substance is made. For example, the changing of the state of ice water into liquid water. A new product is not formed in this reaction hence, it is not a chemical reaction.
