Question $8$

$\frac{0}{1}pts$

The chemical reaction shown below is found to be endothermic, with the magnitude of the net chemical energy change equal to $11eV.$ If the magnitudes of the binding energies for bonds A and $C$ are $5eV$ and $3eV,$ respectively, what is the magnitude of the binding energy for bond B$?($Your answer should be an exact number in units of $eV.)$
