Direct answer
In Chemistry, this page helps you answer questions about crude oil within Carbon compounds as fuels and feedstock. Focus on the key process, correct scientific terms, and how the idea links to exam-style questions. Key terms to check are Crude oil and Hydrocarbon.
Key terms
- Crude oil: A finite resource found in rocks, consisting of a mixture of a very large number of compounds.
- Hydrocarbon: A compound consisting entirely of hydrogen and carbon atoms, commonly found in crude oil.
Common trap
Misidentifying crude oil as a single compound: Explain that crude oil is a heterogeneous mixture containing thousands of different molecules, mainly hydrocarbons, and that this diversity is why fractional distillation is needed to separate useful fractions.
