When writing thermochemical equations for combustion, the fuel source must have a coefficient of 1. This way, the energy value will represent the energy released when 1 mol of fuel burns. As a result, you end up having to put a fraction in front of the oxygen molecule to balance the equation in this particular example.
This guy helped me a lot
Glad to help!
hi can i ask why in example number 4, why is it 5/2 when you can just simply right it as 5? would it make any difference?
