How do homogeneous mixtures differ from heterogeneous ones?

A mixture is a physicochemical system that contains two or more chemical components.
Mixtures, in turn, are divided into homogeneous (homogeneous) and heterogeneous (heterogeneous).
Homogeneous (homogeneous) mixture – a mixture in which its components cannot be distinguished visually.
Homogeneous mixtures can be divided according to their state of aggregation into solid, liquid and gaseous.
For example, air is a homogeneous mixture of various gases.
Homogeneous mixtures are metal alloys, solutions of salt, sugar in water.
Inhomogeneous (heterogeneous) mixture – a mixture in which the components of the mixture can be distinguished visually.
For example: a mixture of water and flour, a mixture of water and sunflower oil.
