2C4H10O + 12O2 -> 8CO2 + 10H2O ΔH=973kJ d) According to the measured data‚ as the alcohol molecules become larger‚ the enthalpies of the combustion become larger too therefore‚ the bigger the molecule‚ the more energy is released. The prediction I made was correct. e) Sources of experimental error in this experiment can be if you didn’t measure the alcohol right after it was burned. If you spilled any alcohol.
