use the average energy listed in the textbook to estimate how much more energy is released by the following reactionC(s) + O2(g) --> CO2(g) O double bond O 495kj than by the reaction for C tripple bond O 1072C(s) + 1/2 O2(g) --> CO(g) C double bond O 743do not use mathematical signs in your answerthe bond for O2 are O double bond O.C double bond O x2 for the first reaction and in the second reaction the CO has a tripple bond i've tried to do this several times and have gotten 166.5 kj/mol 81kj/mol and 48.5 kj/mol and all of them are wrong so i tried 719 + 495 - 2(743) and got -272 then i did the 2nd one719 + 1/2(495) - 1072 and got -105.5
