Answer
Answer:
D. A new substance forms with different properties.
Brief Explanation:
In a chemical change, a chemical reaction occurs when two substances combine. This results in the formation of a new substance with different chemical and physical properties than the original substances. Releasing an odor or changing color can be signs of a chemical change but are not the defining outcome. A new substance with identical properties would not be a chemical - change result.
