Answer:
When two or more substances, that do not react chemically, are blended together,
the result is a mixture in which each component retains its individual identity and
properties.
The separation of the components of a mixture is a problem frequently encountered
in chemistry. The basis of the separation is the fact that each component has a
different set of physical and chemical properties. The components are pure substances
which are either elements or compounds. Under the same conditions of pressure and
temperature, the properties of every sample of a pure substance are identical. Each
sample melts at the same temperature, boils at the same temperature, has the same
solubility in a given solvent, etc.

Answer:
- Scientific question: does life exist on other planets?
- Non-scientific question: there are aliens that look like people?
Explanation:
A scientific question is a coherent question that can be used to develop a scientific hypothesis. Thus, a scientific question must be testable, verifiable, measurable and relevant to the topic of study. In the scientific method, the hypothesis is subsequently tested by experimental or observational procedures, where the results can be used to understand some particular aspect of the real world. On the other hand, a non-scientific question is a light conjecture which cannot be proved by using the scientific method.
