The so-called hydrogen economy is based on hydrogen produced from water using solar energy. The gas is then burned as a fuel: 2H2(g) + O2(g) - 2 H₂O (1) A primary advantage of hydrogen as a fuel is that it is nonpolluting. A major disadvantage is that it is a gas and therefore is harder to store than liquids or solids. Calculate the volume of hydrogen gas at 22 °C and 1.00 atm required to produce an amount of energy equivalent to that produced by the combustion of kg KJ a gallon of octane (C8H18). The density of octane is 2.66 and its standard enthalpy of formation is -249.9 Assume that the products of the gal mol CO2 (g) and H2O (1).
