Given the following information: Heat of sublimation of Li(s) = 166 kJ/mol
Bond energy of HCl = 427 kJ/mol
Ionization energy of Li(g) = 520. kJ/mol
Electron affinity of Cl(g) = -2349 kJ/mol
Lattice energy of LiCl(s) = -2829 kJ/mol
Bond energy of H₂ = -432 kJ/mol
Calculate the net change in energy for the following reaction:
2Li(s) + 2HCl(g) --> 2LiCl(s) + H₂(g)

Which is the layer underground where all empty spaces are filled with a combination of air and water ?
