b) The elements in Group 0 of the periodic table are called the noble gases.
They are unreactive because their atoms have stable arrangement of
electrons. Candidates should know that the noble gases have 8 electrons in
their outer shell except for helium, which has 2 electrons.…

b) Calcium carbonate can be decomposed by heating (thermal
decomposition) to make calcium oxide and carbon dioxide.
c) The carbonates of magnesium, copper, zinc, calcium and sodium
decompose on heating in a similar way
Knowledge and understanding of metal carbonates is limited to metal
carbonates decomposing on…

C1.4 Crude oil and Fuels
Crude oil is derived from an ancient biomass found in rock. Many useful
materials can be produced from crude oil. Crude oil can be fractionally
distilled. Some of the fractions can be used as fuels. Biofuels are produced from
plant material. There…

are required, other than the fact that they are formed at high temperature.
Solid particles may contain soot (carbon) and unburnt fuels.
b) The combustion of hydrocarbon fuels releases energy. During
combustion the carbon and hydrogen in the fuels are oxidised.
c) Sulfur dioxide and oxides of…

Knowledge is limited to the high-energy content of vegetable oils, the
possible health benefits of unsaturated fats compared with saturated
fats, and the effects of cooking foods in oil. Information may be
provided in examinations for candidates to evaluate.
Evaluate the use, benefits, drawbacks and risks of…

hydrogenated oils have higher melting points so they are solids at room
temperature, making them useful as spreads and in cakes and pastries.
Candidates should know how and why vegetable oils are hardened for use in
foods. Knowledge of trans fats is not required. Examination questions may…
