This question asks us to write a balanced equation for the reaction and identify the limiting reactant.
00:05
So part a.
00:07
Let's write out the balanced equation.
00:09
Well, we see that we have some blue -red molecules and we have some red -red molecules.
00:16
So the blue -red ones are going to be no, nitric oxide.
00:21
And then the red -reds are going to be diatomic oxygen, which is o2.
00:25
And what we produce? in our products, we see that we have some red -reds.
00:31
And then we also have some red -blue -red.
00:34
So the red -blue -red is actually going to be n -o -2.
00:39
We're going to ignore the red -red for now, because as you can see, it's the same as our reactant.
00:45
So this is basically indicating to us that we have some excess of this red -red.
00:49
All right.
00:50
So how do we balance this equation? well, are we balanced in terms of our nitrogens? yes, we are.
00:55
But our oxygens aren't balanced...
