Asked by Harold
Two new metallic elements have been discovered, Cimium (Ci) and Sadowium (Sd). Both the pure elements and their solutions form simple cubic lattices. The bond strengths of the Ci-Ci and Sd-Sd bonds are known, but not the Ci-Sd bond.
Bond Bond Energy (kJ/mole)
Ci-Ci -245
Sd-Sd -191
J-R ??
Mixing a solution of 40% cimium and 60% sadowium is an endothermic process. According to your calorimeter, the solution draws 44.6 kJ/mol of heat when mixed. What is the strength of the Ci-Sd bond? Please give your answer in kJ/mol.

Use the equation:
delta(w)= 2w(A-B)-w(A-A)-w(B-B)
delta(w)= 44.6
(A-A)Ci-Ci=-245
(B-B)Sd-Sd=-191
44.6 = 2w(A-B)-(-245)-(-191)
w(A-B) = [44.6 - 245 - 191]/2
w(A-B)= -195.7
-195.7
delta(w)= 2w(A-B)-w(A-A)-w(B-B)
delta(w)= 44.6
(A-A)Ci-Ci=-245
(B-B)Sd-Sd=-191
44.6 = 2w(A-B)-(-245)-(-191)
w(A-B) = [44.6 - 245 - 191]/2
w(A-B)= -195.7
-195.7
