Calculate the enthalpy of reaction for the equation using the bond energy values given. HCCCH3 + H₂ → H₂CCHCH3 -> H H-CEC C-H H H Bond Energy Bond Bond Bond Energy (kJ/mol) AH = [?] kJ (kJ/mol) C-H 413 C-C 348 H-H 436 C=C 602 O-H 463 C=C 839 Include a + or - sign AND the magnitude in your answer. Enter H-H

S+ 8- H-F This is an example of a bond.

[References] The compound oxygen difluoride is quite reactive, giving oxygen and HF when treated with water: OF2(g) + H20(g)→ 0g) + 2HF(g) =-318 kJ ot Using bond energies, calculate the bond dissociation energy of the O-F bond in OF7.
