Now, when I go from step six to seven, I basically want to add these equations up, right? I want to add my two half reactions. So I add all the guys on the left side, and then I add all the guys on the right side. So I get this whole guy plus nothing more on this side. So I go down to my other reactions, plus two of these guys, plus 16 of these guys, plus ten electrons. And now I'm done with everything on the left side.
