Use these values to calculate the energy change (in kJ) for the combustion of 24.8 grams of propane? If your answer is positive include no sign, if it is negative, include a negative sign. kJ
Part ACalculate the bond energy per mole for breaking all the bonds in methane, CH4.Express your answer to four significant figures and include the appropriate units.ΔHCH4 =1656 kJmolCorrectIn CH4, the energy required to break one C−H bond is 414 kJ/mol. Since there are four C−H bonds in CH4, the energy ΔHCH4 for breaking all the bonds is calculated asΔHCH4=4×bond energy of C−H bond=4×414 kJ/mol=1656 kJ/mol CH4 moleculesPart BCalculate the bond energy per mole for breaking all the bonds of oxygen,...
the enthalpy change in a chemical reaction can be determined using bond energies. energy must be added or absorbed to break bonds and that energy is released when bonds are formed. therefore ,you can calculate the total enthalpy of the reaction using following formula: dH= bonds broken-bonds formed Using bond energies, calculate the change in energy that accompanies the following reaction: H2 + O2 -> 2H2O Bond Bond Energy H-H 432 kJ/mol O-O 498 kJ/mol H-O 467 kJ/mol

10. Bond energies like those found in your book can be found by working backwards from reactions in which all but one or two of the given bond energies are already known. For example, the energy change associated with the combustion of formaldehyde is -465 kJ/mol. Given this and the following equation, calculate the energy of the C-O double bond in formaldehyde. Compare this to the listed bond energy for C-O in carbon dioxide and speculate as to why there...
