[Trying]

I havent taken basic chem in a while and I just started an orgo class. I'm trying to figure out how to do a complete combustion reaction. I watched this video http://www.youtube.com/watch?v=azyRhMQziGwand set off to do it.

I thought I had it all figured out then I checked the answers and it's apparent I missed something. I scanned in my work, included the correct answer and the formula I was using.

Thanks!

You're not really wrong, the instructor just multiplied both sides by two to clear the decimals.
