The definition of a fuel, including the distinction between fossil fuels (coal, natural gas, petrol) and biofuels (biogas, bioethanol, biodiesel) with reference to their renewability (ability of a resource to be replaced by natural processes within a relatively short period of time)
Fuel sources for the body measured in kJ g-1: carbohydrates, proteins and lipids (fats and oils)
Photosynthesis as the process that converts light energy into chemical energy and as a source of glucose and oxygen for respiration in living things:
6CO2(g) + 6H2O(l) → C6H12O6(aq)+ 6O2(g)
Oxidation of glucose as the primary carbohydrate energy source, including the balanced equation for cellular respiration:
C6H12O6(aq) + 6O2(g) " 6CO2(g) + 6H2O(l)
Production of bioethanol by the fermentation of glucose and subsequent distillation to produce a more sustainable transport fuel:
C6H12O6(aq) → 2C2H5OH(aq) + 2CO2(g)
Comparison of exothermic and endothermic reactions, with reference to bond making and bond breaking, including enthalpy changes (∆H) measured in kJ, molar enthalpy changes measured in kJ mol-1 and enthalpy changes for mixtures measured in kJ g-1, and their representations in energy profile diagrams
Determination of limiting reactants or reagents in chemical reactions
Combustion (complete and incomplete) reactions of fuels as exothermic reactions: the writing of balanced thermochemical equations, including states, for the complete and incomplete combustion of organic molecules using experimental data and data tables

Problem Solving Exercises
Exercises 1.2 - 1.7
These will check your comprehension of specific topics
Exercise 1.8 Chapter Review, pages 47 - 58
These will check your ability to bring together the whole of the chapter content
Note: You may not need to do every problem to develop a good understanding, but you should do enough so that you are sufficiently challenged
Fossil fuels and biofuels presentation
Note: this was assigned through Google Classroom for you to complete the missing bits
Fuel combustion presentation
This is a supplement to Chapter 1.3
Thermochemical problem - approaches to problem solving
Note: This presentation goes through three different approaches to solving a thermochemical problem given as an example in Chapter 1.4.
