Cars with internal combustion engines burn gasoline (octane, C8H18) but an alternative electric vehicle burns hydrogen gas to generate electricity. Although gasoline is a mixture of hydrocarbons, it can be represented as consisting only of octane, C8H18. a. Write the equation for the combustion of hydrogen gas. This is a synthesis (combination) reaction with water vapor as the product. b. Draw Lewis structures for all molecules in the combustion of hydrogen equation.. c. Use bond energies and Lewis structures to calculate the energy released in the combustion of hydrogen. Use the bond energies table HERE . You can also find this information in week 9, Wk9_Energy_Stoichiometry_notes . d. Which fuel, octane or hydrogen, has a higher fuel value? Octane has a fuel value of 5140 kJ/mol. Express the fuel value in kJ/g. e. Calculate the amount of energy released when 400.0 g of hydrogen are combusted
