Select all that apply Which of the following statements correctly describe the Bom-Haber cycle? Select all that apply. The Born-Haber cycle applies Hess's law to a series of hypothetical steps in the formation of an ionic compound. The Born-Haber cycle finds that the overall lattice energy of an lonic compound compensates for the energy needed to form its lons. The Born-Haber cycle applies Hess's law to show thalion formation supplies sufficient energy to form the lattice. The Born-Haber cycle includes lattice energies, which are determined directly tiy experiment. The Born-Haber cycle uses heats of formation, ionization energies, and electron affinities to determine the lattice energy of an ionic compound.

Given the following thermochemical equation, what is the standard heat of formation for NaOH? 2NaOH(s)-->2Na (s) + O2 (g) + H2 (g) TriangeH= +875.6 kJ a) 875.6 kJ b) -875.6 kJ c) 437.6 kJ d) -437.6 kJ e) 1751.1 kJ f) -1751.1 kJ
