What would you properly conclude about the physical properties and the composition if a certain mixture is homogeneous?

A mixture is homogenous when they are the same in every small volume element of the sample. This means that even though it can be sampled many times, the mixture will still remain the same all throughout. Take note that a homogenous mixture can be in the form of solid, liquid, or gas.

The opposite of this is the heterogeneous mixture which means that some parts of the mixture are not uniform. There are some portions of it that can be separated from each other. Take note that homogeneous mixtures that cannot be separated from each other can also be called substance.
