Hi, I find the equations as written quite confusing. As written, the first equation suggests that an additional 8 free electrons are produced by the reaction which would not balance the equation. Eight electrons are transferred in the reaction for oxidation of sulfide with oxygen to yield sulfate and protons. There should be no free electrons. If you want to convey that 8 electrons are transferred in this reaction, I would use a different convention. If part of the 8 electrons are used to reduce CO2, then less oxygen would be reduced. Thanks! ````
