Hess referred to his set of ideas as "Hess's Law." This concept primarily focuses on the principle of conservation of energy in chemical reactions, stating that the total enthalpy change during a reaction is the same regardless of the number of steps or the pathway taken. Hess's Law is foundational in thermodynamics and is used to calculate the heat changes in chemical processes.
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.

no... because no one can explaine the hess'slaw
Common Hess Law problems include determining the enthalpy change of a reaction using given enthalpy values of other reactions, and calculating the overall enthalpy change of a reaction using Hess's Law. These problems can be solved by carefully balancing the chemical equations, manipulating the given enthalpy values, and applying the principle that enthalpy changes are additive.
The cosmic background radiation was discovered in 1964 by American radio astronomers Arno Penzias and Robert Wilson
