Energy is required to break a covalent ... We can use these bond enthalpies to approximately calculate the enthalpy change for a given reaction.

one simple method is simply to take the coupon rate on the bond to calculate the semi-annual bond payment and then divide it by the current price of the bond to get a yield. Coupon rates are ...

Pauling deduced his electronegativity values from thermo-chemistry using the energies of some chemical bonds. He proposed the simplest formula to calculate a bond's stabilization due to the difference ...
