Okay, so for six a aluminum chlorine or an elemental form. So their oxidation numbers are zero over here in aluminum chloride, we have a negative one on the chlorine and then you have a positive three on the aluminum. So this chlorine is going from zero to a negative one. So it's gaining electrons. So it is reduced.
That means that this is the oxidizing agent and then your aluminum is going from zero to a plus three. So that means it is losing electrons. So that means it is oxidized. And we would say that the aluminum is the reducing agent. Okay, and let her be, we've got a negative to oxidation state for the oxygen, which means hydrogen as a plus one in M N.
+04. We've got a negative two on the oxygen and then a positive seven on the Mn. Because mn plus a negative eight on the oxygen equals negative one. So, if you solve for M and that's how you get that plus seven. This is a mono atomic ion, which is plus two.
So is this, this is a plus three. Another mono atomic ion, plus two, oxygen is a negative two, hydrogen is a plus one here, you'll see that you're going from f plus two, two plus three. So we're losing electrons. So this is oxidized. That means that every plus two is the reducing agent.
And then you've got your Mn going from a plus seven, two plus two. So this is gaining electrons. So this is reduced. So that means that the and then is actually your oxidizing agent there. Okay, then, if you take a look at see, we've got a negative two on the sulfur plus two on the iron here, we have a negative two on the oxygen plus five on the nitrogen because nitrogen plus a negative six on the oxygen is a negative one, solve for the nitrogen, you're gonna get a plus five oxidation state, negative two on the oxygen here, plus one on the hydrogen, negative two on the oxygen plus two on the nitrogen, negative two on the oxygen plus six on the sulfur.
Because sulfur plus a negative eight on the oxygen is going to be a negative to sulfur sulfur, you're gonna end up with a plus six, then this is a mono atomic eye on it, plus three and then oxygen is a negative two hydrogen as a plus one. So here you'll see that the nitrogen is going from a plus five to plus two. So it's gaining electrons. So it's reduced. So that means that this is going to be the oxidizing agent.
And then you've got this F. E. Going from a plus two, two plus three and the sulfur, those both are. That's a loss of electrons. So that means that this is oxidized and this is going to be your reducing agent.
