To use Hess Law, one simply uses the known equations and their respective ∆H values, rearranges them as necessary to arrive at the target equation (unknown ∆H) and then adds the ∆H values to obtain the value for the target equation. This is possible because Hess Law applies to state functions which are independent of the path.

Why it is necessary to mention physical states of reactants and products in thermochemical reaction by hess's law?
Hess's law is important to thermochemistry because it allows us to anticipate enthalpy changes of reactions that are too slow to realistically record, such as rusting or reactions that are too fast. Hess's law, stating that the enthalpy is the same regardless of the pathway, allows us to take known enthalpy values and substituting them in to find your target reaction's enthalpy change.
