Combustion releases energy to the surroundings; at constant pressure this is described by a negative enthalpy change.
Konkrete Kontroll
The mole connects a laboratory-scale mass to an enormous number of particles. Balanced equations turn that counting idea into reaction ratios; thermochemistry then tracks energy transferred.
