The energy change is the difference between the energy of the reactants and the energy of the products.

Calorimetry is an experiment that can be used to measure the energy released from a fuel such as alcohol.

The molecular formula shows the actual number of atoms of each element in a molecule of a compound.

Combustion is an exothermic reaction where a substance reacts with oxygen.

Alcohols are a homologous series that contain the -OH functional group.
