(115 pts.) Ferrous nitrate reacts with silver nitrate in aqueous solution to form ferric nitrate and metallic silver according to the chemical equation

Fe(NO3)2(aq) + AgNO3(aq) + Fe(NO3)3(aq) + Ag(s),

for which K = 3.0.

(a) Derive the net ionic equation for this reaction.

(b) Determine whether the reaction is a replacement reaction or an oxidation-reduction

reaction, and, in the latter case, identify the oxidizing and reducing agents.

(c) Write the expression for Q in terms of the activities (the [] symbols) of the species

responsible for driving the reaction to equilibrium.
