Transition metals chem (redox)Watch
Yeah I meant reduced sorry .. But when I did the equation I wrote it as O2 +2e- --> 2O- , isn't this the reduction equation!😭
The "rules" for balancing redox half-equations are that you can only use:
In acid medium: H+ and H2O
In basic medium: OH- and H2O
How do we know which kind of balancing to do???? Like if there were oxide ions in the products would mine have been correct???
Your second question probably, as you will only get oxide ions formed in things like the combustion of metals.
2Mg + O2 --> 2MgO
IMHO rather too trivial for a redox question.
