No, I probably wasn’t clear about the question.
Whether the carbon is in the form of 20 methanes or of two decanes, the number of carbons and thus, CO2 produced from burning is the same. But the methanes have 80 hydrogens total while the decanes have 44 total hydrogens.
I wanted to know how that affects energy content. Which holds more energy per carbon, the 20 methanes or the two decanes?
seriously??
OBVIOUSLY if you compare two molecules with equal number of carbons and one has more hydrogens than the other, then OBVIOUSLY there is more energy in the molecule with more hydrogens. So like I said before...its all about the carbon to hydrogen ratio.
I’m not going to look it up for you, but there is a known amount of BTUs released for breaking a hydrogen bond and a known amount of BTU’s released for breaking a carbon bond. Oxidizing carbon produces more energy than oxidizing hydrogen. But those hydrogens are not zero. They contribute to the total amount of energy released.
Carbon content of fuels goes something like this(with lowest carbon content first)
hydrogen
methane
propane
butane
gasoline
diesel/kerosene/jet fuel
heating oil
bunker C
tar
asphalt
obviously pure hydrogen has zero carbon content.
