What you will learn
In this course students will learn exactly what they need to know for their chemistry exams so that they can learn as efficiently as possible.
Calculate percentage yield
Understand why covalent substances do not conduct electricity
Understand why ionic substances conduct electricity when molten or aqueous
Apply the terms cation and anion to charged particles
Describe electrolysis experiments and predict the observations made at the anode and cathode
Write ionic half-equations for reactions occuring at the anode and cathode during electrolysis
Know that metals are extracted from compounds that are found in the Earth's crust, and that unreactive metals are often found as uncombined elements
Know how the position of a metal in the reactivity series is linked to the method used for extraction
Comment on a suitable method of extraction for a metal given information pertaining to its reactivity
Explain the uses of metals related to their properties
Describe experiments to investigate the factors that affect the rate of a chemical reaction
Describe the effect on the rate of a reaction of changing the surface area, concentration, temperature, or addition of a catalyst
Explain the effect of the above factors on the rate of reaction in terms of collision theory
Know that a catalyst is a substance that speeds up a reaction but is unaffected by the end of the reaction
Know that a catalyst works by providing an alternative pathway for reaction with a lower activation energy
Draw and explain reaction profiles showing enthalpy change and activation energy
Know that some reactions are reversible and this can be represented with a double arrow
Describe reversible reactions such as those involving hydrated copper sulphate, and ammonium chloride
Know that a reversible reaction can reach a dynamic equilbirium in a sealed container
Describe the features of a dynamic equilibrium
Understand why a catalyst does not affect the position of an equilibrium
Describe the effect of changing the temperature and/or pressure on the position of an equilibrium
Know the definition of a hydrocarbon

Draw possible structural formulae of a molecule given its molecular formula
Understand how to classify reactions as combustion, substitution, and addition
Know the crude oil is a mixture of hydrocarbons
Describe the industrial separation of crude oil using fractional distillation
Know the names and uses of the main fractions obtained from crude oil
Know the trend in colour, viscosity, flammability, and boiling point of the fractions
Know that fuels are substances that release heat when burned
Know the possible products of combustion of hydrocarbons
Understand why CO is poisonous related to its effect on transport of oxygen in the body
Know that cars produce nitrogen oxides due to reaction between nitrogen and oxygen in the car engine
Explain how the impurities in fuels results in the production of sulphur oxides
Explain how non-metal oxides contribute to acid rain
Describe how long chain alkanes are converted into shorter alkanes (and alkenes) in the process of cracking
Explain why cracking is necessary in terms of supply and demand of different fractions

Know that alcohols contain the functional group -OH
Understand how to draw the positional isomers of alcohols
Know that alcohols can be oxidised by combustion, and heating with acidified potassium dichromate
Know that ethanol can be manufactured by the reaction of ethene with steam, and by fermentation of sugars by yeast
