C)Periodic law
D)Hess's law
E)Avogadro's number

Question

Quizplus · Accepted Answer

The Born-Haber cycle relates the formation of a solid ionic compound from its constituent elements to the lattice energy, which is related to the electrostatic interaction between ions in the solid. This involves a series of steps, including ionization energy, electron affinity, and enthalpy of formation, which can be described using Hess's law. Therefore, determining lattice energy from Born-Haber cycle data requires the use of Hess's law. Coulomb's law is a fundamental principle that governs electrostatic interactions between charged particles, but it is not sufficient on its own to determine lattice energy. The octet rule and periodic law are general principles that govern the behavior of atoms, but they are not directly relevant to lattice energy calculations. Avogadro's number is a constant that relates the number of particles in a sample of matter to its mass, and it is not directly relevant to lattice energy calculations.
