So the first part of this question really throws you for a curveball.
00:04
It tells you first and foremost that you have to balance.
00:06
It says it's unbalanced.
00:08
So if we put it to here, that balances our hydrogens.
00:13
We have two oxygens with co2.
00:15
Two oxygians here.
00:17
So now we need another coefficient here.
00:19
And now we have a balanced chemical reaction in which we can work.
00:22
So there's different ways to approach this problem.
00:25
I prefer doing multi -step conversions because it helps me with my rounding.
00:31
Doesn't mess up my rounding.
00:33
So the question itself is asking us to convert grams of methane into grams of carbon dioxide and then ask us to calculate the percent yield of carbon dioxide.
00:44
So it says that you have 16 grams of methane, and we need to convert that to moles.
00:52
That's the way this works.
00:53
So for every one mole of methane, it is 16 grams of methane...
