Suppose a chemist discovers a new metallic element and names it "Xtrinsium" (Xt).
Xt exhibits chemical behaviour similar to an alkaline earth.
Xt(s) + Cl2(g) --> XtCl2(s)
Lattice energy for XtCl2-1960 kJ/mol
First Ionization energy of Xt 480 kJ/mol
Second Ionization energy of Xt 816 kJ/mol
Electron affinity of Cl-348.7 kJ/mol
Bond energy of Cl2 239 kJ/mol
Enthalpy of sublimation (atomization) of Xt 160 kJ/mol
Use the above data to estimate delta H°f for Xtrinsium chloride.
