A list of all chemical substances constituting a mixture is called Mixture composition.
The chemical properties of mixtures may differ from those of any constituent components.
Unlike pure substances the mixtures in a state of Thermodynamic equilibrium may see various phases occupy a continuous area in PT Diagram (see for example Vapour Liquid Equilibrium).
In petroleum industry the most popular mixtures are hydrocarbons and water (H2O)
Mixtures with two components are called binary mixtures and apart from a wide practical value they have a zoomed value in academic studies which allow to understand and model behaviour of all mixtures.
A mixture in a fluid state (liquid, gas or supercritical fluid) is called a fluid mixture.
In petroleum industry the most popular mixtures are hydrocarbons and water (H2O).
