Calculate the enthalpy change for the reaction CaF2 + H2SO4 → 2HF + CaSO4, given that the enthalpies change of formation of CaF2, H2SO4, HF and CaSO4 are -1220, -814, -271 and -1434 kJmol-1 respectively. A book I highly recommend is Calculations in AS / A Level Chemistry by Jim Clark, goes into detail with moles but keeps it simple and fun, with plenty of practice questions.
