What is the balanced redox equation for the voltaic cell? Answer is A) 2 Fe2+(aq) + Cl2(g) \rightarrow → 2 Fe3+(aq) + 2 Cl−(aq)B) 2 Fe3+(aq) + 2 Cl−(aq) \rightarrow → 2 Fe2+(aq) + Cl2(g)C) Fe2+(aq) + Cl2(g) \rightarrow → Fe3+(aq) + Cl−(aq)D) Fe3+(aq) + Cl−(aq) \rightarrow → Fe2+(aq) + Cl2(g)E) None of the above is correct, because neither C(s) not Pt(s) appears in any of them.

The lattice enthalpy (formation of ionic solid from ions in the gas phase) for agcl(s) is -916 kj/mol and the hydration enthalpy (dissolution of gaseous ions into water) is -850 kj/mol. how much heat (in joules) is involved in forming 1l of saturated agcl solution (1.8 × 10-4 g / 100 ml water) by dissolving agcl(s)? assume solution volume does not change much upon dissolution. the equations are given below. ag+(g) + cl−(g) æ agcl(s)
