Question

State Hess law of constant heat summation​

Answer 1

Answer:

Hess's Law of Constant Heat Summation (or just Hess's Law) states that regardless of the multiple stages or steps of a reaction, the total enthalpy change for the reaction is the sum of all changes. This law is a manifestation that enthalpy is a state function.

HOPE IT IS HELPFUL

Answer 2

Answer:

This is your answer!!

Explanation:

Hess's Law of Constant Heat Summation (or just Hess's Law) states that regardless of the multiple stages or steps of a reaction, the total enthalpy(a thermodynamic quantity equivalent to the total heat content of a system. It is equal to the internal energy of the system plus the product of pressure and volume.)

change for the reaction is the sum of all changes. This law is a manifestation that enthalpy is a state function.
