Наука се лакше памти када се дефиниција повеже са нечим мерљивим или уочљивим.
For 2 H2 + O2 → 2 H2O, two moles of hydrogen react with one mole of oxygen in the balanced ideal ratio.

Combustion releases energy to the surroundings; at constant pressure this is described by a negative enthalpy change.
Конкретна провера
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.
