Therefore for the above reaction, saying that $\Delta_\mathrm{r}H^\circ = -572~\mathrm{kJ~mol^{-1}}$ means that. If 2 mol of hydrogen were to react with 1 mol of oxygen to form 2 mol of water, the enthalpy change would be -572 kJ. That means that if you multiplied the equation by 2, $\Delta_\mathrm{r}H^\circ$ would also be multiplied by 2.

The SI unit for energy is the Joule (J), but this is often inconvenient for use with other units. Science often uses molecular or quantum mechanics-based units such as the electronvolt or Hartree, and other industries have their own units such as the British Thermal Unit (BTU) for heating, and the kWh (kiloWatt-hour) for domestic electricity comsumption.

The product of the number of moles and the enthalpy change in kJ/mol has the units kJ: (number of moles) ( in kJ/mol) = kJ. We therefore report in kJ. 21.04.2011 The units for the molar heat of fusion are kilojoules per mole (kJ/mol).

ΔH f o = -285.8 kJ mol-1 This means that when molecular hydrogen gas reacts with molecular oxygen gas, 285.8 kJ of energy will be released for every mole of liquid water that is produced. If 10 moles of liquid water was produced from molecular hydrogen gas and molecular oxygen gas, then 10 × 285.8 = 2858 kJ of energy would be released.

Ide o to, že v prípade niektorých potravín (napr. múka), kde je to možné, urobíte dobre ak ich preosejete na plech a pri teplote 90 °C prehrejete na pár minút. Následne presypete do nádoby. X =(1 mole × 4.516 KJ) ÷ 0.1 mole = 45.16 KJ/mol = - 45.16 KJ/mol. The calculated molar energy released (- 45.16 KJ/mol) will not change but the energy released by the reaction where 4.00g are used (4516 joules) would be higher than the energy released by 1.00g NaOH which is 1129 joules. Explanation: Explanations.

Sometimes, the unit J/g is used. In that case, the term heat of fusion is used, with the word 'molar' being eliminated. See Example #3 below. The molar heat of fusion for water is 6.02 kJ/mol.
