So we have the following molecule co, and we have to find the oxidation state for each carbon.
00:09
So we know that the charge for oxygen is 2 minus, and we know there's one atom of oxygen.
00:19
And salt for carbon oxidation state, which is unknown, we label that as an x.
00:24
And there's one atom of carbon, so we multiply that by one.
00:27
And we know that the sums of their charges should be equal to zero.
00:34
So we have x minus 2 is equal to 0, which means that x is equal to positive 2.
00:39
So this is the charge of our carbon.
00:42
Now for part b, we have co2.
00:44
Well, let's see, we said that oxygen has a charge of 2 minus...
