Answer

Brief Explanations:

An element consists of only one type of atom. A pure compound has a fixed - ratio of elements. A pure substance is either an element or a compound. Since the sample of crude oil contains different hydrocarbons (paraffins, naphthenes, aromatics, asphaltic) in different percentages, it is not an element, pure compound or pure substance. A mixture is a combination of two or more substances that are not chemically combined, which is the case for crude oil.

Answer:

a mixture
