Hi everyone. So I asked if the given reaction is a redox reaction and if it is, we need to identify the reaction that is an oxidizing agent and the reacting that as a reducing agent. Recall that the loss of electrons is oxidation and that's going to be the reducing agent in the gain of electrons. It's gonna be a reduction. It's going to be an oxidizing agent. So if we look at the changes in the oxidation states, our study, um we're going from a zero here And this is a -2. This has to be a plus one four plus 1 here, but it has lost electrons and this is going to be the reducing agent for oxygen. We're going from a zero here To a negative two here, but this is gaining electrons and it's going to be an oxidizing agent. So yes, is the readouts reaction because we have oxidation and reduction taking place and the reducing agent, his sodium and the oxidizing agent is oxygen. Thanks for watching my video and I hope it was helpful
