Principles of General Chemistry 2
Define bond energy using the \(\mathrm{H}-\mathrm{Cl}\) bond as an example. When this bond breaks, is energy absorbed or released? Is the accompanying \(\Delta H\) value positive or negative? How do the magnitude and sign of this \(\Delta H\) value relate to the value that accompanies \(\mathrm{H}-\m
