2
Q
how do the carbon atoms join in crude oil
A
joined into chains of different length, hydrogen atoms come off the carbon atoms.
3
Q
when is crude oil useful
A
when it is seperated via boiling point through the use of heat to get different fractions (type of hydrocarbons) out of it.
4
Q
do smaller chains boil at lower temperatures
A
yes , opposite for longer chains.
5
Q
where does fractional distillation occur, for example, to separate crude oil?
A
oil refinery
6
Q
where does oil come from
A
the sea or abroad
7
