ANSWER:

Problem 8.79a(a) Consider the lattice energies for the following compounds: BeH , 3205 kJ/mol; M2 , 2791 2kJ/mol; CaH , 210 kJ/mol; SrH , 2250 2/mol; BaH , 2121 kJ/mol2Plot lattice energy versuscation radius for these compounds. If you draw a line through your points, is the slope negativeor positive Explain. Step-by-step solution Step 1 of 3 The lattice energy for the following compounds is below, BeH = 3205 kJ/mol, 2 MgH = 2791 kJ/mol, 2 CaH =2410 kJ/mol, SrH 2 = 2250 kJ/molAnd BaH = 2121 kJ/mol 2
