Answer:
<u>Homogeneous mixture:</u>
- These are called solutions.
- It has a uniform composition.
- It has only one phase.
- It cannot be separated physically.
- The particles appear smaller in size.
- These are pure substances.
- These are not visible easily visible to the naked eye and also through a microscope.
- Examples include milk, gasoline, sugar solution, corn oil, fog, etc.
<u>Heterogeneous mixture:</u>
- These are called suspensions/colloids.
- It has a non-uniform composition.
- There are two or more phases.
- It can be separated physically.
- The particles are either smaller or larger in size.
- These are not pure substances.
- These are easily visible to the naked eye and also through a microscope
- Examples are- a mixture of mud & water, beach sand, vinegar, air cloud, etc.
Well one mole of stuff, any stuff, including carbon dioxide, specifies

Answer: It can't.
Explanation:
In most cases, the melting point alone will not enable you to identify a compound. Millions of solid organic compounds, and their melting points, are known. Perhaps 10,000 of these will have the same melting point as your unknown compound.
