Question

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 1

1) Answer is:C. Their components can be separated by physical processes.
Mixtures can be separeted physically, while compounds cannot.
For example if we have mixture of water and alcohol ethanol, we can separate water and ethanol with distillation (process of heating and cooling). Ethanol and water have different boiling points (physical property).
