Watch PLANET perform 'Imaginary' Live at Enmore

An imaginary planet was just discovered that has a similar environment to our planet Earth. All the chemistry is similar except for the values of bond energies. Use the planet's given bond energies to calculate the enthalpy of reaction for the combustion of 1 mole of butane.Enter a number to 0 decimal places in kJ/molBondEnergy(kJ/mol)H-H 436C-H 363H-O 508C-C 376C=C 698C≡C 839O=O 499C-O 344C=O 9903,003
