And we combine that with some oxygen, molecular oxygen, it's also a gas.

Because oxygen was the limiting reagent, we only had 1 mole of oxygen here.

You have some oxygen gas or a diatomic oxygen molecule.

Finally, oxygen.

Let's deal with the oxygens.

Let's look at the oxygen.

Discontinue the oxygen.

This is going to be the oxygen molecule, O2.

I don't have enough oxygen.

This draws the oxygen down into the body.

How much oxygen do I have?

You know all about oxygen.

Let's see how much oxygen we're given.

I need 2.5 moles of oxygen.

So oxygen is the limiting reagent.

And then I have a different number of oxygens.

So how many oxygens do I have?

little bit careful here because sometimes people say we have 32 grams of oxygen when they're really talking about the molecular oxygen.

And we're given 32 grams of oxygen.

And we've been given 1 mole of the oxygen molecule.

I only have 1 mole of oxygen.

Remember, I'm going to worry about the oxygen last.

Providing we don't waste our oxygen talking, of course.

So the oxygen can go into this blood and so once the oxygen so this is the vessel that's coming from the heart and then it's just a tube.

But I don't have 2.5 moles of oxygen.

Why don't I put a 2 3 in front of this oxygen.

I took the heads off two cylinders of oxygen and I filled them up with live explosive.

The last factory for the manufacture of oxygen has been destroyed.

You could think of oxgyen kind of being, let's say something like that, well then, relative to that, nitrogen would be you know, much more, right?

They need, for example, let's say oxygen.

The mass of just the atomic oxygen, you have to be a

So how many moles of oxygen have we been given?

So oxygen, in this example, was the rate limiting factor.

And at the end, I'll have some number of oxygens.

Oh,Thank God. If I Didn't Think We Were Running Out Of Oxygen,

Or how much of the molecular oxygen we've been given in this case.

So what's the molecular mass of the diatomic molecule O2?

So oxygen is going to be the limiting reagent in this reaction.

Because then I would have had more than enough oxygen.

How much oxygen is required to completely react with that glucose?

So one thing that I need to pick up is oxygen.

One reason why is, you have all these negative oxygens here.

And on the flip side, is it getting oxygen or nutrients?

So then you have nice flow, and in return, oxygen and nutrients are delivered.

Or for every 5 moles of oxygen we need 4 moles of ammonia.
