E. All answers are incorrectI
I. Causal relationships (20 points)
1. Petroleum and natural gas originating from microorganisms buried for
millions of years.
Because
Petroleum and natural gas are
non-renewable.
2. Crude oil (crude oil) can be separated into several fractions.
Because
Crude oil (crude oil) is a
hydrocarbon compound.
3. LPG is a petroleum fraction of the lightest.
Because
LPG containing 5-12 carbon atoms.
4. Fuel has an octane number of 90 can be classed as fuel poor quality.
Because
Can lead to many knock.
5. The process of separation of petroleum into fractions was based on
differences in their boiling points.
Because
The longer the carbon atom the
higher the boiling point.
