Answer:

B. A mixture has different properties throughout; a pure substance has the same properties throughout

Step-by-step explanation:

We have two classes of substances which are pure and impure substances.

Pure substances are elements and compounds

Impure substance are simply mixtures.

Mixtures have the following properties;

  • Their composition is indefinite i.e. they consist of two or more elements and or compounds in any proportion by mass.
  • Constituents retain their identities i.e. physical properties are retained.
  • Constituents react differently to changed conditions
  • They can easily be separated by physical methods.
