Original post by g_lHere is the triple spec., the bits in bold of the specification *NOT SAYING THAT YOU SHOULD NOT REVISE EVERYTHING ELSE, JUST SAYING TOPICS TO PAY MORE ATTENTION TO. haters quit yo' hatin' *
Section 1: Principles of chemistry
d) Relative formula masses and molar volumes of gases
1.18 understand the term mole as the Avogadro number of particles (atoms, molecules, formulae, ions or electrons) in a substance
1.20 understand the term molar volume of a gas and use its values (24 dm3 and 24,000 cm3) at room temperature and pressure (rtp) in calculations.
e) Chemical formulae and chemical equations
1.26 calculate percentage yield
f) Ionic compounds
1.35 understand the relationship between ionic charge and the melting point and boiling point of an ionic compound
1.36 describe an ionic crystal as a giant three-dimensional lattice structure held together by the attraction between oppositely charged ions
1.37 draw a diagram to represent the positions of the ions in a crystal of sodium chloride.
g) Covalent substances
1.44 draw diagrams representing the positions of the atoms in diamond and graphite
1.45 explain how the uses of diamond and graphite depend on their structures, limited to graphite as a lubricant and diamond in cutting.
i) Electrolysis
1.54 describe experiments to investigate electrolysis, using inert electrodes, of aqueous solutions such as sodium chloride, copper(II) sulfate and dilute sulfuric acid and predict the products
1.56 recall that one faraday represents one mole of electrons
1.57 calculate the amounts of the products of the electrolysis of molten salts and aqueous solutions.
Section 2: Chemistry of the elements
b) Group 1 elements — lithium, sodium and potassium
2.8 explain the relative reactivities of the elements in Group 1 in terms of distance between the outer electrons and the nucleus.
Section 3: Organic chemistry
d) Ethanol
3.9 describe the manufacture of ethanol by passing ethene and steam over a phosphoric acid catalyst at a temperature of about 300°C and a pressure of about 60–70 atm
3.10 describe the manufacture of ethanol by the fermentation of sugars, for example glucose, at a temperature of about 30°C
3.11 evaluate the factors relevant to the choice of method used in the manufacture of ethanol, for example the relative availability of sugar cane and crude oil
3.12 describe the dehydration of ethanol to ethene, using aluminium oxide.
Section 4: Physical chemistry
b) Energetics
4.12 calculate molar enthalpy change from heat energy change
4.16 use average bond energies to calculate the enthalpy change during a
simple chemical reaction.
Section 5: Chemistry in industry
c) Synthetic polymers
5.16 draw the repeat unit of addition polymers, including poly(ethene), poly(propene) and poly(chloroethene)
5.18 describe some uses for polymers, including poly(ethene), poly(propene) and poly(chloroethene)
5.20 understand that some polymers, such as nylon, form by a different process called condensation polymerisation
5.21 understand that condensation polymerisation produces a small molecule, such as water, as well as the polymer.
d) The industrial manufacture of chemicals
5.26 recall the raw materials used in the manufacture of sulfuric acid
5.27 describe the manufacture of sulfuric acid by the contact process, including the essential conditions:
i a temperature of about 450°C
ii a pressure of about 2 atmospheres
iii a vanadium(V) oxide catalyst
5.28 describe the use of sulfuric acid in the manufacture of detergents, fertilisers and paints
5.29 describe the manufacture of sodium hydroxide and chlorine by the electrolysis of concentrated sodium chloride solution (brine) in a diaphragm cell
5.30 write ionic half-equations for the reactions at the electrodes in the diaphragm cell
5.31 describe important uses of sodium hydroxide, including the manufacture of bleach, paper and soap; and of chlorine, including sterilising water supplies and in the manufacture of bleach and hydrochloric acid.
And that's it people.... remember, these are just the triple statements and they may test you on things on the double statement that they didn't test you on Monday. GOOD LUCK.
