Combustion of alcohols: planning
I can write balanced symbol equations for combustion of alcohols and investigate the energy changes of combustion reactions.
These resources will be removed by end of Summer Term 2025.
Lesson details
Key learning points
- Balanced symbol equations can be written for the combustion of alcohols.
- It is difficult to measure directly the energy change of a reaction.
- Calorimetry can be used to measure a reaction's energy change indirectly.
Keywords
Energy change - The energy change is the difference between the energy of the reactants and the energy of the products.
Calorimetry - Calorimetry is an experiment that can be used to measure the energy released from a fuel such as alcohol.
Molecular formula - The molecular formula shows the actual number of atoms of each element in a molecule of a compound.
Combustion - Combustion is an exothermic reaction where a substance reacts with oxygen.
Alcohols - Alcohols are a homologous series that contain the -OH functional group.
Common misconception
Forgetting to measure the initial mass of the burner and initial temperature of the water.
Emphasise the importance in remembering to measure this data when writing a method for this practical.
Equipment
None, planning lesson only.
