Q4.18: In order to break a F-F bond, an energy of 153 kJ is required per mole of F-F bonds. What wavelength of light would be required to break a single F--F bond? Answer: nm
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,...
A carbon-iodine bond strength is listed as 241.0 kJ/mol. What energy is required to break a single C-l bond? What wavelength of light (nm) corresponds to a photon that contains enough energy to break a C-l bond? Would a C-H (443.3 kJ/mol), require a shorter or longer wavelength to be broken?
How much energy is associated with a mole (6.022 x 1023) of photons with a frequency of 4.30 x 1014 s-1 ( Answer in kJ to 3 sig figs)
Interconverting wavelength, frequency and photon energy It takes 157 kJ/mol to break a nitrogen-oxygen single bond. Calculate the maximum wavelength of light for which a nitrogen-oxygen single bond could be broken by absorbing a single photon. Round your answer to 3 significant digits. x 5 ?
According to your textbook, the bond energies for a C=O bond and an O=O bond are 803 and 498 kJ per mole, respectively. Double-check the table to make sure that these values are correct. Based on those values for bond energies, calculate the energy released in this reaction. Your answer should have units of kJ per mole of CO2 formed. C + 02 → CO2
