The so called hydrogen economy is based on hydrogen produced from water using solar energy. The gas may be burned as a fuel: 2H2 (g) + O2 (g) ---> 2H2O (l) A primary advanatge of hydrogen as a fuel is that it is nonpolluting. A major disadvantege is that it is a gas and therefore is harder to store than liquids or solids. Calculate the volume of hydrogen gas at 25oC and 1.00 atm required to produce an amount of energy equivalent to that produced by the combustion of a gallon of octane (C8H18). The density of cotane is 2.66 kg/gal and its standard entalpy of formation is -249.9 kj/mol.
