So we're to direct the nitrogen ions from highest chloros oxidation states.
00:06
So we're given the following nitrogen containing molecules, n3 minus, n2h5 plus, n03 minus, nh4 plus, and lastly, n02 minus.
00:28
Okay, so if we look at our first molecule, we see that it's an n3 with a minus term.
00:33
And since this is this a nitrogen atom, it's overall oxidation state or oxidation or not, yeah, that an oxidation state is negative 1.
00:48
Now for our second one, we have n2h5 plus.
00:55
So we know there's two nitrogen.
00:57
So that's two times our oxidation number plus five times hydrogen, which has a plus one charge.
01:03
And the overall charge is plus 1.
01:06
So we get 2x plus 5 is equal to 1.
01:11
To check 5 from both sides, we get 2x is equal to negative 4, which means that x is equal to negative 2.
01:18
That is our oxidation charge.
01:21
Our number is 2 minus for nitrogen.
01:24
Now for our next one, we have n, which is the oxidation number we're trying to find, which is x plus 3 times oxygen, which has a 2 minus charge and its overall charge is equal to negative 1...
