Okay, so for this problem, this type of reaction where you have a carbohydrate plus oxygen yield co2 and h2o, every time will be a combustion reaction.
00:12
So this is a combustion reaction.
00:14
With combustion reactions, you're always going to balance the carbon first.
00:18
So carbon is one in one, so we are good.
00:20
The next thing you'll balance is the hydrogen.
00:22
So you have four hydrogen on your reactant side.
00:25
Therefore, you need four hydrogen on your product side.
00:28
And then the last thing you'll balance the oxygen.
00:30
So we have four on our product side, so we need four on our reactant side.
00:34
So now our equation is balanced.
00:39
So then we're told that there are 55 moles of ch4, and we're asked to convert it to moles of h2o, grams of h2o, molecules of h2l.
00:48
So we're going to start by converting the moles to moles.
00:52
So if we start with our 55 moles of ch4, if we start with moles of ch4, that means moles of ch4 has to go in the bottom...
