WebDec 9, 2024 · In the second step of the reaction, two moles of H-Cl bonds are formed. Bond breaking liberates energy, so we expect the ΔH for this portion of the reaction to have a negative value. Using the table, the single bond energy for one mole of H-Cl bonds is found to be 431 kJ: ΔH 2 = -2 (431 kJ) = -862 kJ. By applying Hess's Law, ΔH = ΔH 1 + … WebThe Lewis structure is a way of representing the valence electrons in a molecule and the bonds between atoms.
