Bacterial digestion is an economical method of sewage treatment. the reaction 5co2(g) + 55nh4+(aq) + 76o2(g) > c5h7o2n(s) + 54no2-(aq) + 52h2o(l) + 109h+(aq) is an intermediate step in the conversion of the nitrogen in organic compounds into nitrate ions. what mass of bacterial tissue is produced in a treatment plant for every 1.0 x 104 kg of wastewater containing 3.0% nh4+ ions by mass? assume that 95% of the ammonium ions are consumed by the bacteria.
