The property of being able to add enthalpies is based on the:
- A
Law of Conservation of Heat
- B
First Law of Thermodynamics
- C
Law of Constants
- D
Law of E = mc2
- E
Hess"s law
The law states that the total enthalpy change during the complete course of a chemical reaction is independent of the sequence of steps taken.
The law of conservation of energy states that energy can neither be created nor destroyed - only converted from one form of energy to another.
The First Law of Thermodynamics states that energy cannot be created or destroyed; it can only be converted from one form to another.
The law of constant proportions states that chemical compounds are made up of elements that are present in a fixed ratio by mass.
the equation says that energy and mass (matter) are interchangeable; they are different forms of the same thing.
The law states that the total enthalpy change during the complete course of a chemical reaction is independent of the sequence of steps taken
