To find the enthalpy of formation of a compound, you can use the enthalpy changes of reactions that involve the elements that make up the
compound, even if those reactions are not necessarily intermediate steps in the production of that compound
Known enthalpy changes can be combined to calculate unknown enthalpies of reaction
If a reaction contains intermediate steps, the overall enthalpy change is equal to the last step where the enthalpy changed.
Thermochemical equations may be reversed, if necessary, to calculate unknown enthalpies, as long as the sign of the enthalpy value also changes.

What is Hess's Law?

Hess's Law is also referred to as Hess's law of constant heat summation and it was named after a Swiss-born Russian chemist called Germain Hess.

Hess's Law states that the energy change experienced in an overall chemical reaction is equal to the sum of the energy changes in each chemical reactions that it contains.

In conclusion, the enthalpy change of a chemical reaction which is the heat of reaction at constant pressure is independent of the pathway between its initial and final states.
