This problem took quite a bit of writing, and you can see what i've got here.
00:05
I've got three bubbles, and each bubble contains methanol and o2.
00:10
And we are given the following chemical reaction that i've written here, and we're asked how many co2s for each bubble.
00:17
Let's do a first.
00:19
A contains 1, 2, 3 ch3oh and 3 o2.
00:35
So let's figure out how many co2s this could make using the balanced chemical equation.
00:39
Equation.
00:40
3 ch3oh can make, it's a 2 to 2 mole ratio, can make 3 co2s.
01:02
And 3 o2s can produce, this is 2 moles and 3 moles, will be 9 divided by 2 will equal 4 and a half.
01:33
So i can make 3 three co2 molecules.
01:42
Now just as a quick check here, if i produce three co2 molecules, i'd produce six of these, and that'd be six, plus six is 12, two, four, six.
02:07
Am i doing this right? i have three ch3os, two, seven, eight, nine, so i have 10 o2s.
02:49
I'm just thinking right now, i'm going to pause.
02:52
I don't know what i'm doing here.
02:53
This is my wrong one...
