3. An underground storage tank has sprung a leak, sending 184 kilograms of ethanol into the subsurface soil. Ethanol can be used as an electron donor under either aerobic (oxygen is the electron acceptor) or sulfate reducing (sulfate is reduced to H2S) conditions. a) How many electrons are transferred during the oxidation of ethanol (C2H5OH) to carbon dioxide (CO2)
