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.
