You can see that the lattice enthalpy of magnesium oxide is much greater than that of sodium chloride. That's because in magnesium oxide, 2 ions are attracting 2- ions; in sodium chloride, the attraction is only between 1 and 1- ions. The radius of the ions The lattice enthalpy of magn...

Calculate the enthalpy of reaction for HCN(g) to H(g) + C(g) + N(g) from standard enthalpies of formation. Given that the C-H bond enthalpy is 411 kJ/mol, obtain a value for the C-N bond enthalpy. Calculate the standard enthalpy change for the reaction of...

The Born-Haber cycle may also be used to calculate any one of the other quantities in the equation for lattice energy, provided that the remainder is known. For example, if the relevant enthalpy of sublimation ΔHs°, ionization energy (IE), bond dissociation enthalpy (D), lattice energy ...

What is bond dissociation enthalpy? Which kind of energy is stored in a chemical bond? What is the relative atomic mass of potassium? What are the properties of sodium chloride? Describe the composition of potassium chlorate KClO3 What properties characterize ionic compounds?
Since the lattice formation enthalpy is electrostatic in nature, too, we can say that it depends on similar factors such as the charges of the ions, their sizes, and their arrangement in the solid. Thus, for a given arrangement of ions, the lattice energy increases as the charges on the...
