(a)
Crude oil is a
2n+2 alkanes carbon condense distillation evaporating formula fractional fractions hydrocarbon hydrocarbons hydrogen mixture molecules n not number physical saturated separate separating structure temperatures unchanged of a very large number of
2n+2 alkanes carbon condense distillation evaporating formula fractional fractions hydrocarbon hydrocarbons hydrogen mixture molecules n not number physical saturated separate separating structure temperatures unchanged compounds.
(b) A
2n+2 alkanes carbon condense distillation evaporating formula fractional fractions hydrocarbon hydrocarbons hydrogen mixture molecules n not number physical saturated separate separating structure temperatures unchanged consists of two or more elements or compounds
2n+2 alkanes carbon condense distillation evaporating formula fractional fractions hydrocarbon hydrocarbons hydrogen mixture molecules n not number physical saturated separate separating structure temperatures unchanged chemically combined together.
(c) The chemical properties of each substance in the mixture are
2n+2 alkanes carbon condense distillation evaporating formula fractional fractions hydrocarbon hydrocarbons hydrogen mixture molecules n not number physical saturated separate separating structure temperatures unchanged .
(d) It is possible to
2n+2 alkanes carbon condense distillation evaporating formula fractional fractions hydrocarbon hydrocarbons hydrogen mixture molecules n not number physical saturated separate separating structure temperatures unchanged the substances in a mixture by
2n+2 alkanes carbon condense distillation evaporating formula fractional fractions hydrocarbon hydrocarbons hydrogen mixture molecules n not number physical saturated separate separating structure temperatures unchanged methods including distillation.
(e) Most of the compounds in crude oil consist of
2n+2 alkanes carbon condense distillation evaporating formula fractional fractions hydrocarbon hydrocarbons hydrogen mixture molecules n not number physical saturated separate separating structure temperatures unchanged made up of
2n+2 alkanes carbon condense distillation evaporating formula fractional fractions hydrocarbon hydrocarbons hydrogen mixture molecules n not number physical saturated separate separating structure temperatures unchanged (H) and
2n+2 alkanes carbon condense distillation evaporating formula fractional fractions hydrocarbon hydrocarbons hydrogen mixture molecules n not number physical saturated separate separating structure temperatures unchanged (C) atoms only which is why they are called
2n+2 alkanes carbon condense distillation evaporating formula fractional fractions hydrocarbon hydrocarbons hydrogen mixture molecules n not number physical saturated separate separating structure temperatures unchanged .
(f) Most of these are
2n+2 alkanes carbon condense distillation evaporating formula fractional fractions hydrocarbon hydrocarbons hydrogen mixture molecules n not number physical saturated separate separating structure temperatures unchanged (meaning all single C-C bonds) hydrocarbons called
2n+2 alkanes carbon condense distillation evaporating formula fractional fractions hydrocarbon hydrocarbons hydrogen mixture molecules n not number physical saturated separate separating structure temperatures unchanged , which have the general formula C
2n+2 alkanes carbon condense distillation evaporating formula fractional fractions hydrocarbon hydrocarbons hydrogen mixture molecules n not number physical saturated separate separating structure temperatures unchanged H
2n+2 alkanes carbon condense distillation evaporating formula fractional fractions hydrocarbon hydrocarbons hydrogen mixture molecules n not number physical saturated separate separating structure temperatures unchanged (g) Alkane molecules can be represented in the following forms:
is a way of summarising the atoms in the molecule, and is called the molecular
2n+2 alkanes carbon condense distillation evaporating formula fractional fractions hydrocarbon hydrocarbons hydrogen mixture molecules n not number physical saturated separate separating structure temperatures unchanged .
is a way of showing the full molecular
2n+2 alkanes carbon condense distillation evaporating formula fractional fractions hydrocarbon hydrocarbons hydrogen mixture molecules n not number physical saturated separate separating structure temperatures unchanged .
(h)The many hydrocarbons in crude oil may be separated into
2n+2 alkanes carbon condense distillation evaporating formula fractional fractions hydrocarbon hydrocarbons hydrogen mixture molecules n not number physical saturated separate separating structure temperatures unchanged , each of which contains molecules with a similar
2n+2 alkanes carbon condense distillation evaporating formula fractional fractions hydrocarbon hydrocarbons hydrogen mixture molecules n not number physical saturated separate separating structure temperatures unchanged of carbon atoms.
(i) This is done by
2n+2 alkanes carbon condense distillation evaporating formula fractional fractions hydrocarbon hydrocarbons hydrogen mixture molecules n not number physical saturated separate separating structure temperatures unchanged the oil and allowing it to
2n+2 alkanes carbon condense distillation evaporating formula fractional fractions hydrocarbon hydrocarbons hydrogen mixture molecules n not number physical saturated separate separating structure temperatures unchanged at a number of different
2n+2 alkanes carbon condense distillation evaporating formula fractional fractions hydrocarbon hydrocarbons hydrogen mixture molecules n not number physical saturated separate separating structure temperatures unchanged .
(j) This process of
2n+2 alkanes carbon condense distillation evaporating formula fractional fractions hydrocarbon hydrocarbons hydrogen mixture molecules n not number physical saturated separate separating structure temperatures unchanged the components of crude oil is called
2n+2 alkanes carbon condense distillation evaporating formula fractional fractions hydrocarbon hydrocarbons hydrogen mixture molecules n not number physical saturated separate separating structure temperatures unchanged 2n+2 alkanes carbon condense distillation evaporating formula fractional fractions hydrocarbon hydrocarbons hydrogen mixture molecules n not number physical saturated separate separating structure temperatures unchanged .
