This thermodynamic cycle describes the formation of an ionic compound $Mx$ from a metal element $M$ and nonmetal element $x$ in their standard states. Use it to

answer the questions in the table below. What is the lattice enthalpy of MX$?$ What is the heat formation of MX$?$ Suppose both the ionization enthalpy of M and the heat of sublimation of M were bigger. Would Mx be more stable or less?
