What is the difference between a homogeneous and a heterogeneous mixture? what is the difference between a homogeneous and a heterogeneous mixture?
a. a homogeneous mixture consist of compounds in the same state, while a heterogeneous mixture consist of compounds in different states.
b. a homogeneous mixture has the same composition throughout, while a heterogeneous mixture has different compositions in different regions.
c. a homogeneous mixture has different compositions in different regions, while a heterogeneous mixture has the same composition throughout.
d. a homogeneous mixture consist of only one compound, while a heterogeneous mixture consist of two or more compounds.

Option (B).

Explanation:

Mixture may be defined as the solution obtained by mixing of two or more substances together. Two different types of mixture are homogeneous mixture and heterogeneous mixture.

Homogeneous mixture may be defined as the mixture that has uniform composition throughout the mixture and cannot be separated easily by physical shaking process. Heterogeneous mixture are the mixtures that has different composition throughout the mixture and can be separated by simple shaking.

Thus, the correct answer is option (B).
