Answer to Question #289318 in General Chemistry for gus

Question

#1) Using Quantum Theory to explain give the stable ions that Ge and Bi can form.

#2) The following series of equations represent a method of decomposing water vapour to produce hydrogen and oxygen.

1) 6 FeCl2(s) + 8 H2O(g) + 636 kJ → 2 Fe3O4(s) + 12 HCl(g) + 2 H2(g)

2) Fe3O4(s) + 3/2 Cl2(g) + 6 HCl(g) → 3 FeCl3(s) + 3 H2O(g) + ½ O2(g) + 249 kJ

3) 3/2 FeCl2(s) + 3/4 Cl2(g) → 3/2 FeCl3(s) - 87 kJ a)

Show that the net result of the three reactions is the decomposition of water. b) Use Hess’s law and the enthalpy changes for the reactions to determine the enthalpy change for the decomposition of one mole of water.
