So over this question, we're asked to figure out how many moles of water are produced if we have one and a half moles of the c5h12.
00:09
So first we have to balance the equation.
00:14
So if we look, we have five carbons on the left, but only one on the right.
00:19
So we'll put a five coefficient in front of the carbon dioxide.
00:22
Now we have five and five.
00:25
Next, let's look at the hydrogens.
00:27
We have 12 on the left, but only two on the right.
00:30
So let's put a six coefficient.
00:32
Front of the water.
00:34
Now we have 12 hydrogens on each side.
00:37
Then we'll go to the oxygen last.
00:40
So on the left hand side, we have two oxygens.
00:42
And then on the right hand side, we have 10 oxygens from the carbon dioxide and six oxygens from the water.
00:50
So we have a total of 16 oxygens.
00:52
So if we put an eight coefficient in front of the oxygen on the left, eight times two is 16.
01:01
So now we have 16 oxygens on each side...
