The question states which of the following is the free energy change of combustion for ethanol under standard conditions? A chart is given in the passage with the different values for free energy
I get this is a simple implementation of Hess' Law. But my question is don't we need to write out a balanced equation first and the calculate the free energy value. The answer key when making the balanced equation disregards O2. It simply writes ethanol --> 2H2O + 2CO2
Why didn't they put the O2...
