Methane is produced using anaerobic digestion of acetic acid. if 0.56 g of co2 is produced per g acetic acid consumed, calculate the yield of methane from the substrate (g methane/g acetic acid). assume that ammonia is the sole nitrogen source and the biomass formula is ch 1.2o 0.4n 0.2.

Silver tarnishes as silver metal reacts with hydrogen sulfide, h2s, in the air. in this reaction, dark silver sulfide, au2s, covers the surface of silver. when silver is polished, this coating of silver sulfide can be removed from the surface. this makes the silver shiny again. enter the coefficients that balance the tarnishing reaction equation. (type 1 for no coefficient.)
