Asked by Emma
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?

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.
