Answer:
Mixtures, on the other hand, are considered impure substances. A mixture is created when substances combine but no chemical reaction occurs. ... Pure compounds and elements differ from mixtures in one key way: the substances in a pure compound are held together by chemical bonds. These chemical bonds cannot be broken.
