... change in enthalpy for whole process is the same, regardless of whether you use Hess’s law or heats of formation. In this way enthalpy is a state function. 3) What is meant by “Energy is quantized”? Energy can only be certain values. For example, the 1s orbital has a certain energy and the 2s orbita ...
