A Level Chemistry - enthalpy changes
Hi, could someone clarify how you'd calculate the enthalpy change for each of these:
And a rough idea of what practical experiment you should carry out to calculate these enthalpy changes? I know for the combustion of alcohols you'd set up a spirit burner and a calorimeter and record the temp change of the water, but how about for the others?
Would really appreciate any help

measure the change in temperature
make sure you know all the masses (or moles etc.) of the species involved, including any water present
polystyrene cup, lid, thermometer
