Water and oil do not mix with each other. It is a mixture.
A mixture of oil and water is a mixture, not an element. If by substance you mean not a pure substance (element or compound), then oil and water would be a substance (that is a mixture). If you mean oil and water separately, then oil is a mixture of hydrocarbons, and water is a compound (pure substance).
It is a mixture.
No because it is not an element. It is a mixture of 3 aromatic isomers found in crude oil.
Examples of a mixture is oil and water, element is copper and a solution is salt and water.
A mixture is a combination of different molecules that can be separated using physical methods, like filtrata combination of different molecules that can only be separated using chemical meanssy to separate and this can be done just by letting them settle out into their layers. This is a physical process and therefore the combination of oil and water is a mixture.

Hydrogen* is neither a mixture nor a compound it is a basic element. Compounds are combinations of elements such as H20 (water molecule and 2 oxygen molecules) and mixtures are combinations of substances such as mixing oil and water.
Sunflower oil is a mixture. This means that a bunch of sunflower seeds had their oil extracted to make the bottle of oil.
No because it is not an element. It is a mixture of 3 aromatic isomers found in crude oil.
Oil and vinegar form a heterogeneous mixture.
It is a mixture. It is not an element or a compound, so it has to be a mixture. Plus, almost all oils are mixtures, as in if you set them out long enough, they wil separate. This process may take a while, though.
Oils are mixtures of organic compounds.
It is neither, it is an element
It is a complex mixture of compounds. See related link.
