Question 6 If a 1.315 M solution of Fe(NO3)3(aq) fully dissociates in water, what is the concentration of nitrate ions in Molarity, M? Just give the number, the assumption is the unit is molarity, M. It might be helpful to write a dissociation equation. 10 pts

Question 8 10 pts Give the net ionic equation for the reaction (if any) that occurs when aqueous solutions of K₂S and Fe(NO3)2 are mixed. O Fe²+ (aq) + S2 (aq) + 2 K+ (aq) + 2NO3(aq) → FeS(s) + 2 K+ (aq) + 2NO3(aq) No reaction occurs. O Fe²+ (aq) + s² (aq) + 2 K+ (aq) + 2NO3(aq) → Fe2+ (aq) + S2 (aq) + 2 KNO3(s) O Fe²+ (aq) + S² (aq) → FeS(s) O K+ (aq) + NO3(aq) → KNO3(s)
