True or False? Fix the false ones
Circle T or F for each statement. If the statement is false, rewrite it correctly on the line below.
Crude oil is used only as a fuel source.
Correct it:
Replacing fossil fuels with renewables for electricity generation is easier than replacing petrochemical feedstocks for plastics and chemicals.
Correct it:
Catalytic cracking uses a zeolite catalyst to break long hydrocarbon chains into shorter, more useful ones at lower temperatures than thermal cracking.
Correct it:
Cracking always produces alkanes as its only products, no alkenes are formed.
Correct it:
Ethene produced by cracking can be polymerised to make polyethylene.
Correct it:
1. Name TWO products made from crude oil that are used as feedstocks (not burned as fuels). For each product, state what it is made into.
2. What is the energy transition? Name TWO types of renewable energy that could replace fossil fuels for generating electricity.
