5.The heat combustion of acetylene, , at 25°C, is -1299 kJ/mol. At this temperature, the enthalpy of formation for and are -393 and -286 kJ/mol, respectively. Calculate for acetylene.

6. For O2, , and , draw the molecular orbital (MO) diagram, fill in the electrons, and calculate the bond order for each. Which one has the strongest bond? Please draw clearly to receive full credit. For your convenience, you can draw only one MO diagram, but you must clearly indicate the electrons for each molecule and ions.
