Which statement best describes the difference between a heterogeneous mixture and a homogeneous mixture?
A
A homogeneous mixture contains only one type of element, while a heterogeneous mixture contains multiple elements.
B
A heterogeneous mixture can only exist as a solid, while a homogeneous mixture can only exist as a liquid.
C
A homogeneous mixture can be separated by filtration, while a heterogeneous mixture cannot.
D
A heterogeneous mixture has visibly different components or phases, while a homogeneous mixture has a uniform composition throughout.

Understand the definitions of mixtures: A mixture is a combination of two or more substances where each substance retains its own chemical identity.
Recognize that a homogeneous mixture has a uniform composition throughout, meaning you cannot see different parts or phases with the naked eye.
Know that a heterogeneous mixture has visibly different components or phases, so you can distinguish the different parts physically.
Eliminate incorrect statements by checking if they align with the definitions: for example, mixtures are not limited to solids or liquids, and filtration depends on particle size, not mixture type.
Conclude that the best description is that a heterogeneous mixture has visibly different components or phases, while a homogeneous mixture is uniform throughout.
