Assume that an extremely inefficient electrical utility company delivers electrical energy to your home from a natural gas-burning power plant with an overall efficiency of only 21% and your furnace is 100% efficient in converting electrical energy into heat energy.What mass of natural gas must be burned by the power plant if heating your home requires 3.5 × 10⁷ kJ? The heat of combustion of natural gas is 50.1 kJ/g. A)1.5 × 10⁵ g B)3.3 × 10⁶ g C)3.7 × 10⁸ g D)8.4 × 10⁹ g
