Write and balance each combustion equation; i.e.,
CH4 + 2O2 ==> CO2 + 2H2O
Then dHrxn = (n*dHf products) - (n*dHf reactants).
Ethane and ethanol are done the same way. You can find delta Hf values in your text or notes.
In your search for fuel to use after the reserves of gasoline dry up, you decided to analyze different compounds (2 hydrocarbons & an alcohol) by combustion. You independently combust methane (CH4), ethane (CH3CH3), and ethanol (CH3CH2OH) at 298 K and 1 atm.
What is the delta H reaction for the combustion of each of these fuels?
