Explanation / Answer
A) Write a net ionic equation for the reaction that occurs when aqueous solutions of sodium hydroxide and hydrocyanic acid are combined.
answer : OH- (aq) + HCN (aq) --------------------> CN- (aq) + H2O (l)
B) Write a net ionic equation for the overall reaction that occurs when aqueous solutions of potassium hydroxide and carbonic acid are combined. Assume excess base.
answer : 2OH- (aq) + H2CO3 (aq) ------------------> 2H2O (l) + CO2 (g)
C) Write a net ionic equation for the reaction that occurs when aqueous solutions of hydrofluoric acid and ammonia are combined.
answer : HF (aq) + NH3 (aq) ----------------------> NH4F (aq)
D) Write a net ionic equation for the reaction that occurs when aqueous solutions of ammonia andhydrochloric acid are combined.
answer : NH3 (aq) + H+ (aq) ----------------------> NH4+ (aq)
E) Consider the reaction when aqueous solutions of cobalt(II) sulfate and lead(II) acetate are combined. The net ionic equation is:
answer : Pb+2 (aq) + SO4-2 (aq) -------------------> PbSO4 (s)
F) Consider the reaction when aqueous solutions of iron(II) sulfate and chromium(II) acetate are combined. the net ionic equation is:
answer : Cr+2 (aq) + SO4-2 (aq) -------------------> CrSO4 (s)
