Question

1.) Refer to the table given for the ionic radii in your lab manual and approximate the attractive portion of the lattice energy for 1 mole of the following salts. (Consider only one bond if more than one bond exists.)

(a)    MgS
______ J

(b)    Fe₃N₂
______J

(c)    CoCl₂
______ J

2.) Using the values you just calculated, rank the salts from least to most soluble based on their attractive portion of their lattice energy. (Use the appropriate <, =, or > symbol to separate substances in the list.)
