Hi there.
00:03
This is problem 3 .2.
00:07
And in this problem we are told that hydrogen, and we see hydrogen there in the drawing is existing as h2, and they give us that formula for it.
00:18
So hydrogen is reacting with co, and it is forming c -h3 -oh.
00:33
That's important to realize this equation that i just wrote is unbalanced.
00:41
This is not a balanced equation.
00:42
But then they also give us the drawing for the hydrogen.
00:52
They give us eight molecules of the hydrogen.
01:02
I don't necessarily have my molecules drawn in exactly the same location, but they're gas, so they're moving around.
01:07
All right, so there are eight of those, and the question wants to know, and we'd like us to draw the co.
01:17
Well, let's go back to the formula for the product.
01:25
What we see there is a total of four hydrogen, for every co.
01:39
So for one co, we would need four total hydrogen.
01:43
So let's look at our hydrogen over here.
01:47
Remember, there are two in each molecule...
