Need help with understanding this hess cycle as oxygen is not really taken into account; why is that? Also , what are the equations suggesting. I get that the elements will form 6CO2 AND 6H20 to make the products but there is not enough oxygen though...
I have but it's really messy. I just don't really understand it. I get that 6c will form 6 co2 meaning 6*-394 and 6H2 form 6H2O so 6*-286 . This is the reverse of -2801, which will now be 2801. But in order to form 6 co2 and 6 water, you need you have 21 o but there are only 6 in the equation, how does it work?? I am referring to 6c .

There's a mistake in the question. The formation of H2O should have 1/2 O2, not 1 1/2.
Have a look at the equation for the combustion of glucose. It has 12 extra O atoms in it.
This is the part I'm confused with.
This is how I interpret it: to form 6 co2 you need 12 oxygen + 6 oxygen to form 6 water. Altogether you need 18 oxygen as reactants but there is only 6 oxygen available as far as I can see in the original equation. Without enough oxygen, how is the reaction supposed to work to form carbon dioxide and water that will form C6H12O6??
