Answer :
Final answer:
Natural gas is primarily methane and ethane, while crude oil consists of thousands of organic compounds, primarily hydrocarbons. The differences in boiling points allow for crude oil's separation into different fractions.
Explanation:
Natural gas primarily consists of methane and ethane, while petroleum (crude oil) is composed of thousands of organic compounds, primarily hydrocarbons. The boiling point differences allow for the separation of crude oil into various fractions.
Natural gas forms primarily from methane (CH4) and is often found above oil deposits. On the other hand, oil is a viscous liquid composed of various hydrocarbons. Natural gas is in gaseous form, while oil is a liquid.
Coal, oil, and natural gas are all fossil fuels primarily made of hydrocarbons, but they differ in states of matter and chemical compositions. Coal is solid, oil is liquid, and natural gas is gaseous.
