In this exercise, we are given three little windows, and i've tried to draw these windows for you, and we're given the reaction you see right here.
00:09
So we have methanol reacting with oxygen to yield carbon dioxide and water.
00:18
And we are asked to do two things.
00:20
We are asked to pick which window, let's call them a, b, and c, produces the most products.
00:37
Most products.
00:39
And after we have that figured out, we're also going to use that window to tell how many co2 molecules will form.
00:47
Okay.
00:49
So the black particles represent carbons.
00:53
So we can cross out b right away because there's only one carbon here.
00:58
And one carbon and four hydrogens doesn't give me very much.
01:02
It would let me do a half a particle of hydrogen.
01:06
Let's look at, i just know the answer here, so i'm going to do it this way.
01:10
In reaction window c, we have four carbons.
01:20
We have four times four, 16 hydrogens, and we have two, four, six, eight, oxygens.
01:35
Looking at our products, and i'm just gonna write our products right here, we have two co2 plus four h2...
