This thermodynamic cycle describes the formation of an ionic compound MX from a metal element M and nonmetal element X in their standard states. Based of the table (picture): A. What is the lattice enthalpy of MX2? (in kJ/mol) B. What is the enthalpy of formation of MX2? (in kJ/mol) C. Suppose the electron affinity of X were bigger and the heat of sublimation of M were smaller. Would MX2 be more or less stable? Or would it be impossible to tell without more information?
2. A 35 g metal ball made up of a mixture of element X and element Y is heated up to 77C and dropped into 20 mL of 15°C water.
