🤓 Based on our data, we think this question is relevant for Professor Pollock's class at MSU.
Before we split the reaction into half reactions, we must determine the oxidation numbers of each atom in the reaction
For O2 and Co in the reactant side, both will have 0 as its ON since it's in its atomic form
Separate this redox reaction into its component half-reactions.
3O2 + 4Co → 2Co 2O3
