hw 6l7b

How would you balance the redox reaction: H+(aq) + OH-(aq) --> H2O(l), the Brønsted neutralization reaction?
In the answer key, they use o2(g) to balance out the oxygens, but how would you know to do that?

You can probably assume both of the electrodes are exposed to air since they are not normally closed cells. Therefore, oxygen plays a role in both the anode and cathode half reactions.

Are galvanic/volteric cells normally closed? I though they were open but in that case O2 would be available in other redox reactions and that doesn't seem to be the case.
