Gases, petrol, kerosene, diesel oil, fuel oil and bitumen are the fractions obtained from crude oil by fractional disitillation. what fraction is more difficult than most other fractions and is used as a fuel in large ships?
Name of fraction: FUEL OIL
1 of 8
what fraction is obtained from the top of the fractionating column?
Name of fraction: GASES

how does carbon monoxide (CO) cause death?
Carbon monoxide can cause death as it goes into the red blood cells and destroys the parts that carry oxygen when you breath it in, so it can sufficate you.

Biofuels are produced from plants. what is a problem caused by growing plants to produce biofuels?
Problem would be that it uses up land, which could be used for other things eg. food-meaning there is a shortage of food & is quite expensive.

alkenes are unsaturated hydrocarbons. what is meant by unsaturated?
MEANING: unsaturated hydrocarbon is where it has a double carbon bond.

Propane and Propene are bubbled through seperate samples of bromine water. Describe what you would see in these tests.
Answer: the Propane will stay a yellowish orange colour (because bromine water is originally yellow), but the propene will turn clear.

in industry, long chain hydrocarbon molecules are cracked to form shorter chain hydrocarbons molecules. Explain why this process is important.
Answer: Because shorter chains ignite easier and flow better, this process is important as short chain hydrocarbons are much more useful they ignite and flow easier, and things like petrol which are in high demand are short chain hydrocarbon
