Which of the following is true about homogeneous mixtures
a. they are known as solutions
b. the consist of two or more phases
c. they have compositions that never vary
d. they are always liquids.
separating a solid from a liquid by evaporation the liquid is called
a. filtration
b. condensation
c. solution
d. distillation

The answer to this question would be: 
A. They are known as solutions 
D. Distillation

The homogenous mixture will mix the solute with the solvent completely, make them spread in equally. It will be called dissolved. In this case, the mixture will not be able to be separated easily.

One way to separate a homogenous mixture that is by heating them so the solvent evaporates. This can be done for a mixture with different evaporation temperature. By evaporating the solvent, you will force the solvent move without the solute. This process was called distillation. The example use of this method would be when separating salt from seawater
