Resource summary

Question 1

Question
Is a crude oil a mixture of many hydrocarbons?
Answer
  • True
  • False

Question 2

Question
Click what a hydrocarbon is made from...
Answer
  • Made from carbon atoms and others.
  • Made from hydrogen and carbon and oxygen atoms.
  • Made from hydrogen and carbon ONLY.

Question 3

Question
Click all that apply... Why are fossil fuels described as finite resources and non-renewable?
Answer
  • They never run out.
  • Finite resources are no longer being made or are being made very slowly. Non-renewable energy resources are used up faster than they can be replaced.
  • They run out eventually.

Question 4

Question
Tick ALL problems that are associated with the finite nature of crude oil...
Answer
  • All the readily extractable resources will be used up in the future.
  • The species of synthesised unicorns depend on drinking the crude oil in order to retain their sparkly awesomeness.
  • Finding replacements.
  • Conflict between making petrochemicals and fuels.

Question 5

Question
In the fractional distillation of crude oil:- Crude oil is [blank_start]heated.[blank_end] The fractionating column has a temperature [blank_start]gradient[blank_end] ([blank_start]cold[blank_end] at the top and [blank_start]hot[blank_end] at the bottom). Fractions containing [blank_start]mixtures[blank_end] of hydrocarbons are obtained. The fractions contain many substances with [blank_start]similar[blank_end] boiling points. Fractions with low boiling points exit from the [blank_start]top[blank_end] of the column. Fractions with high boiling points exit from the [blank_start]bottom[blank_end] of the fractionating column.
Answer
  • heated.
  • gradient
  • cold
  • hot
  • mixtures
  • similar
  • top
  • bottom

Question 6

Question
LPG contains [blank_start]propane[blank_end] and [blank_start]butane.[blank_end]
Answer
  • propane
  • butane.

Question 7

Question
Click the potential environmental problems involved in the transportation of crude oil...
Answer
  • Damage to birds' feathers, causing death.
  • Detergent used to clean up oil slicks and consequent damage to wildlife.
  • It'll make the clouds sad.

Question 8

Question
The hydrocarbons in crude oil can be separated by fractional distillation because the [blank_start]covalent[blank_end] bonds between carbon and hydrogen atoms within a hydrocarbon are [blank_start]stronger[blank_end] than the [blank_start]weaker[blank_end] intermolecular forces between hydrocarbon molecules.
Answer
  • covalent
  • stronger
  • weaker

Question 9

Question
Intermolecular means [blank_start]between the molecules[blank_end] during boiling, intermolecular forces are [blank_start]broken[blank_end] but [blank_start]covalent[blank_end] bonds are not.
Answer
  • between the molecules
  • broken
  • covalent

Question 10

Question
Intermolecular forces between large hydrocarbon molecules are [blank_start]stronger[blank_end] than those between smaller hydrocarbon molecules.
Answer
  • stronger

Question 11

Question
Check the political problems associated with the exploitation of crude oil...
Answer
  • UK depends on oil and gas from politically unstable countries.
  • Future supply issues.
  • The Dwarves will finally have enough and start a rebellion led by an inner group enigmatically named 'The BrotherHood'.

Question 12

Question
Cracking crude oil fractions:- Coverts [blank_start]large[blank_end] alkane molecules into smaller [blank_start]alkene[blank_end] molecules . Uses an [blank_start]aluminium oxide[blank_end] catalyst at a [blank_start]high[blank_end] temperature. The alkene molecules made are useful because they can be used to make [blank_start]polymers.[blank_end]
Answer
  • large
  • alkene
  • aluminium oxide
  • high
  • polymers.

Question 13

Question
When crude oil is distilled the volume of each fraction is not the same, we get too many [blank_start]long-chain[blank_end] hydrocarbons than are needed and not enough short-chain hydrocarbons (e.g. [blank_start]petrol[blank_end]) to meet the demand for them. Cracking helps an oil refinery match its supply of useful products (such as petrol) to the [blank_start]demand[blank_end] for them.
Answer
  • long-chain
  • petrol
  • demand

Question 14

Question
List the seven factors to consider when choosing the best fossil fuel:- T[blank_start]oxicity[blank_end] (of fumes) E[blank_start]nergy Value[blank_end] A[blank_start]vailability[blank_end] [blank_start]Cost[blank_end] U[blank_start]sability[blank_end] (light it easily? move it easily?) P[blank_start]ollution[blank_end] (green house effect/smoke) [blank_start]Storage[blank_end] (space used)
Answer
  • oxicity
  • nergy Value
  • vailability
  • Cost
  • sability
  • ollution
  • Storage

Question 15

Question
The amount of fossil fuels being burnt is increasing because of the growth of use in developing countries like India and China, and the world population is increasing... IS THIS TRUE?
Answer
  • True
  • False

Question 16

Question
Choose the word and symbol equations for the complete combustion of a hydrocarbon fuels e.g. methane. (CH4)
Answer
  • CH4 + 2O2 - 2CO2 + H2O
  • CO4+ 2CH + H2O
