Below are the half reactions for sulfate reduction using acetate as a source of electrons, energy, and carbon. CO2 + 8e- -> CH3COO- (-0.29 volts) SO42- + 8e- -> H2S (-0.22 volts) If you balance and combine the reactions so that 29 molecules of CH3COO- are oxidized to CO2, how many electrons are transferred from carbon to sulfur?
