A mixture in which the components can be easily distinguished
B
A pure substance composed of only one type of atom
C
A substance that cannot be separated into simpler substances by physical means
D
A mixture in which the composition is uniform throughout
Verified step by step guidance1
Understand the definition of a homogeneous mixture: it is a mixture where the composition is uniform throughout, meaning you cannot distinguish the different components by simple observation.
Contrast this with a heterogeneous mixture, where the components can be easily distinguished and are not uniform throughout.
Recognize that a pure substance composed of only one type of atom refers to an element, not a mixture.
Note that a substance that cannot be separated into simpler substances by physical means is a pure substance, not a mixture.
Therefore, the best description of a homogeneous mixture is 'a mixture in which the composition is uniform throughout.'
