The given question is incomplete, the complete question is:
Which statement describes both homogeneous mixtures and heterogeneous mixtures?
A.
Their components can be distinguished visually.
B.
Their components are combined in a fixed ratio.
C.
Their components can be separated by physical processes.
D.
They always contain a liquid component.
E.
They are considered to be pure substances.
Answer:
The correct answer is option C, that is, their components can be separated by physical processes.
Explanation:
A combination of two or more substances in which no reaction or chemical combination takes place is termed as a mixture. On the other hand, the atoms of different elements that are combined chemically in a fixed ratio are termed as a compound.
The mixtures, that is, whether homogenous or heterogeneous exhibits the tendency to get differentiated physically, on the other hand, compounds do not possess such a tendency. Like one can separate the mixture of alcohol and water by the process of distillation, as both the components exhibit distinct boiling points, that is, can be separated based on their physical characteristics.
On the other hand, if one desires to distinguish oxygen and hydrogen from water, then there is a need to dissociate the bonds present between the molecules of hydrogen and oxygen, which is its chemical property, not physical characteristics.
