In Iceland, Sweden, and other parts of Scandinavia, where hydroelectric plants produce relatively inexpensive electric power, the H2 can be made industrially by the electrolysis of water. Car manufacturers are developing engines that use H2 as fuel.
1. Determine the numbers of coulombs are required to form the 4.0 x 106 LH2 gas at 12.4 atm pressure and 23°C?
2. Determine the numbers of joules are produced if the coulombs are supplied at the 1.86 V.
3. Explain what mass of oil must be burned to yield the number of joules in the b if the combustion of oil yields 5.0 x 104kJ/kg.
