Neither or both; Benzene C6H6 is a pure compound, not a mixture, thus the liquid and gas state are homogenous. Solid state could be multi-crystalline, but not sure about that (at least depending on low temperature)
They don't dissolve when mixed: heterogeneous
Benezene is Homogeneous
heterogenous
Sugar (sucrose) dissolves completely in water, making a homogeneous solution.
homogeneous
The mixture water-ethanol is homogeneous.
Muddy water is a heterogeneous mixture.
Alcohol and water form a homogeneous mixture.
Sugar (sucrose) dissolves completely in water, making a homogeneous solution.
heterogeneous mixture because it is dissolved by water
homogeneous
The mixture water-ethanol is homogeneous.
A simple water accordingly is a Heterogeneous mixture.
Muddy water is a heterogeneous mixture.
Alcohol and water form a homogeneous mixture.

Homogeneous mixture
The electrolytes will completely dissociate in the water. Therefore it will be a homogeneous mixture.An example of heterogeneous mixture is sand in water.
