Match the following terms with their definitions:
formula mass = The sum of the relative atomic masses of all the atoms present in a formula fraction = A group of hydrocarbons with boiling points within a given range obtained from crude oil by fractional distillation fuel = A substance which burns to produce energy functional group = A group of atoms with characteristic chemical activity, e.g. carboxyl group -COOH
Match the following terms with their examples:
fossil fuel = Coal, crude oil, natural gas glycerol = An alcohol with three -OH groups in each molecule, CH2OHCHOHCH2OH greenhouse gas = Carbon dioxide, CO2 halogens = Reactive non-metals in group 7 of the Periodic Table (F, Cl, Br, I, At)
Match the following terms with their characteristics:
fractional distillation = A means of separating crude oil into groups of hydrocarbons with similar boiling points (fractions) group ion = One which contains more than one kind of atom, e.g. the ammonium ion, NH4+ homologous series = A group of chemically similar compounds which can be represented by a general formula. Physical properties change gradually through the series, e.g. the alkanes hydrocarbon = A compound that contains carbon and hydrogen only
