Hexane is colourless and clear. It's also really syrup-like in consistency with a really harsh smell. I've had loads of bad-smelling experiences in A-Level Chemistry with hexane and cyclohexane!
Pure octane is a clear colorless hydrocarbon liquid.
The only way is Fractional distillation.

Yes it is, because you could see more than one substance in it. Wood and The led. and of course the led and wood could be separated. So the pencil would be considered as mechanical mixture
benzene and water are immiscible liquids. therefore they have to be separated by means of a separating funnel.
For example a mixture of solid materials.

A mixture is when two substances are combined in the same container, but could still be separated. A molecule is the smallest bit of a compound you can possibly have.

Hexane will clean a petroleum, plant or animal based grease but it will not touch silicone based greases.
