WebDec 9, 2024 · 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 + ΔH 2 ΔH = +679 kJ - 862 kJ ΔH = -183 kJ Answer WebJan 30, 2024 · Some of the bonds in the reactants are broken, and new bonds are made to form the products. It costs energy to break bonds, but energy is released when new bonds are made. Whether a reaction is able to go forward may depend on the balance between these bond-making and bond-breaking steps.

WebWhy are the phosphoanhydride bonds considered high-energy? All this really means is that an appreciable amount of energy is released when one of these bonds is broken in a … WebJul 7, 2024 · Enormous energy is present in the bonds that hold the nucleus together. This nuclear energy can be released when those bonds are broken. The bonds can be broken through nuclear fission, and this energy can be used to produce (generate) electricity.
