Question:
Car manufacturers are developing engines that use {eq}H_{2} {/eq} as fuel. In Iceland, Sweden, and other parts of Scandinavia, where hydroelectric plants produce inexpensive electric power, the {eq}H_{2} {/eq} can be made industrially by the electrolysis of water. Enter your answers in scientific notation.
A) How many coulombs are needed to produce {eq}2.4*10^{6} L of H_{2} {/eq} gas at 12.0 atm and 25 degrees Celsius? (Assume the ideal gas law applies.)
B) If the coulombs are supplied at 3.12 V, how many joules are produced?
C) If the combustion of oil yields {eq}4.0*10^{4} {/eq} kJ/kg, what mass of oil must be burned to yield the number of joules in Part B?
