Regarding the chemistry qualitative, revise everything you have done so far. I'm guessing it will be on the enthalpy change of combustion?

Go through the formula that determines ∆H and think about how each variable of the formula (mass, ∆t, mol) affects the overall ∆H.

Think about experimental errors that can lead to an incorrect ∆H too

Good luck

For the enthalpy qualitative, there aren't many tests to know
