- What volume of O2 (g) is collected at 25.0°C and 1.02 atm if 1.00 kg of water is electrolyzed? Given: 2H2O(l) --> O2 (g) + 2H2 (g)Chemical formula of NH4+ and CO32-Excessive nutrients dumped into waterways can create “algae blooms” that rapidly consume all of the dissolved O2 and trigger production of enough H2S to create “dead zones” like the ones that exist off the coast of Denmark and in the Gulf of Mexico immediately south of the Mississippi River delta. a. Since Group 16 element substitution is a recurring theme in that Group’s chemistry –e.g., oxygen substituting for Se and Te in the production of H2Se and H2Te, respectively –maybe molecular oxygen (O2) could be bubbled into these dead zones and react with the H2S.Write out a balanced chemical equation for the reaction between H2S and O2 to form elemental sulfur (S8) as a product that would precipitate out. b. Using bond dissociation energies, calculate if this reaction would be thermodynamically favorable. c. If your answer to part (b) is “yes”, do you think that simply bubbling O2 into these waters would work? Justify your answer.
