This question contains a balanced chemical reaction where we have two molecules of methanol, ch30h, reacting with three molecules of o2, producing two molecules of co2 and four molecules of h2.

Each part of this question shows a diagram containing a certain number of methanol molecules and oxygen molecules, and you are asked to determine how many molecules of carbon dioxide can be created from each scenario, the first scenario is three molecules of methanol and three molecules of oxygen.
00:37
We recognize the stoichiometry from methanol and carbon dioxide is 2 -2.
00:42
So if we have three molecules of methanol, with a stoichiometry 2 -2, we could produce three molecules of carbon dioxide.
00:52
We can do a similar calculation with the three molecules of o2.
00:56
Three molecules of o2 will only produce two molecules of carbon dioxide.
01:01
So if we were mixing three molecules of methanol with three molecules of o2, the maximum amount of carbon dioxide that we could create would be the smaller of the two, just two molecules of carbon dioxide...
