Answer: Because new substances are formed.

Explanation: A chemical property is any of a material's properties that becomes evident during, or after, a chemical reaction; that is, any quality that can be established only by changing a substance's chemical identity.  Once a chemical change occurs it cannot be undone due to the change in chemical identity.  The creation of a new substance is not reversible.
