Helloo!!
According to Hess’s law for a multistep reaction the standard reaction enthalpy is independent of the pathway or number of steps taken, rather it is the sum of standard enthalpies of intermediate reactions involved at the same temperature.
In Simple language
According to this law, the heat Change is always constant when chemical reaction completed in first state and more that first state is called Hess law
Use this formula for solving problems based on Hess law
ΔH = Product - reactants
Note :: Don't include oxygen as a reactant!!

❤.Hess law : "The total heat change in a reaction is the same whether the chemical reaction takes place in a single step or in several steps".
❤.It is based on the I law of thermodynamics .
