The overlap of atoms symbolizes bond strengths, with C-H (brown) and O-O (dark blue) totaling 27 electron volts.  On combustion C-O (black) is a very strong bond and there is also H-O (green) totaling 35 eV.  The difference, 8 eV is “released” or made “available” for human economic use such as heating or driving a vehicle or generating electricity.  At the macro level a kilogram of natural gas delivers 20 megajoules of energy.  What we have overlooked in the past but now need to acknowledge is that the bonds we play with are a small subset of the coulombic forces within each set of atoms.  When the bonds are rearranged from 27eV to 35eV, in order to give of 8eV, they are only numerators and they beg denominators.  In context, in the environment, 27/464 has been changed to 35/456.  Entropy has increased, 5.8 to 7.7.

原子间重叠象征了化学键强度,两个分子共有27电子伏特(eV)。在反应后形成新的两个非常强的化学键,共有36eV。二者之差,9eV就是“释放”或产生的“有用能”,用于人类经济活动如加热、驱动汽车或发电。在宏观水平上,我们过去忽视而现在必须承认的是,我们所了解的化学键只是每组原子之间库仑力的子集。
