Verified step by step guidance

Understand the definition of a homogeneous mixture: it is a mixture that has the same uniform appearance and composition throughout the entire sample.
Recognize that in a homogeneous liquid mixture, the components are evenly distributed at the molecular level, so you cannot see separate parts or layers.
Recall that a homogeneous mixture does not separate into layers over time; that behavior is characteristic of heterogeneous mixtures.
Note that a homogeneous mixture can contain more than one type of molecule, but they are mixed so thoroughly that the composition is consistent everywhere.
Conclude that the key characteristic of a homogeneous liquid mixture is that it has a uniform composition throughout, meaning its properties and appearance are the same in any sample taken.
