  1. 1Is a crude oil a mixture of many hydrocarbons?
    1. ARichtig
    2. BFalsch
  2. 2Click what a hydrocarbon is made from...
    1. AMade from carbon atoms and others.
    2. BMade from hydrogen and carbon and oxygen atoms.
    3. CMade from hydrogen and carbon ONLY.
  3. 3Click all that apply...

    Why are fossil fuels described as finite resources and non-renewable?
    1. AThey never run out.
    2. BFinite 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.
    3. CThey run out eventually.
  4. 4Tick ALL problems that are associated with the finite nature of crude oil...
    1. AAll the readily extractable resources will be used up in the future.
    2. BThe species of synthesised unicorns depend on drinking the crude oil in order to retain their sparkly awesomeness.
    3. CFinding replacements.
    4. DConflict between making petrochemicals and fuels.
  5. 5In 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.
    1. Aheated.
    2. Bgradient
    3. Ccold
    4. Dhot
    5. Emixtures
    6. Fsimilar
    7. Gtop
    8. Hbottom
  6. 6LPG contains [blank_start]propane[blank_end] and [blank_start]butane.[blank_end]
    1. Apropane
    2. Bbutane.
  7. 7Click the potential environmental problems involved in the transportation of crude oil...
    1. ADamage to birds' feathers, causing death.
    2. BDetergent used to clean up oil slicks and consequent damage to wildlife.
    3. CIt'll make the clouds sad.
  8. 8The 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.
    1. Acovalent
    2. Bstronger
    3. Cweaker
  9. 9Intermolecular 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.
    1. Abetween the molecules
    2. Bbroken
    3. Ccovalent
  10. 10Intermolecular forces between large hydrocarbon molecules are [blank_start]stronger[blank_end] than those between smaller hydrocarbon molecules.

    1. Astronger
