To calculate the amount of heat required to break all the bonds in 5 moles of carbon dioxide, we need to consider the bond energy values for the C=O bond. The O-H bond is not relevant in this case, as there are no O-H bonds in carbon dioxide.Carbon dioxide CO2 has two C=O double bonds. The bond energy for a C=O double bond is approximately 799 kJ/mol.First, let's calculate the energy required to break one mole of CO2:Energy = 2 C=O bonds 799 kJ/mol C=O bond energy = 1598 kJ/molNow, let's calculate the energy required to break 5 moles of CO2:Energy = 5 moles 1598 kJ/mol = 7990 kJTherefore, the amount of heat required to break all the bonds in 5 moles of carbon dioxide is 7990 kJ.
