Write a balanced net ionic equation, including phase labels, for each combination of solutions that produced a solid or a gas.

1. NaOH + Na2CO3

2. FeCl2 + Na2CO3

3. AgNO3 + Na2CO3

4. NaOH + AgNO3

5. FeCl2 + AgNO3

Solutions

Expert Solution

1. NaOH + NaHCO3 ----------> Na2CO3 + H2O

balanced total ionic equation = Na+ + OH- + Na+ + HCO3- ----------> 2Na+(aq) + CO32-(aq) + H2O (l)

Net ionic equation = OH- (aq) + HCO3- (aq)---------------> CO32-(aq) + H2O (l)

2. FeCl2 + Na2CO3 -------------> 2NaCl + FeCO3

balanced total ionic equation = Fe2+ + 2Cl- + 2Na+ + CO32- ----------> 2Na+(aq) + 2Cl- (aq) + FeCO3 (s)

Net ionic equation = Fe2+ (aq) + CO3 2- (aq) -------------> FeCO3 (s)

3.2AgNO3 + Na2CO3 ------------> Ag2CO3 + 2NaNO3

balanced total ionic equation = 2Ag+ + 2NO3- + 2Na+ + CO32- ----------> 2Na+(aq) + 2NO3- (aq) + Ag2CO3 (s)

Net ionic equation = 2Ag+ (aq) + CO3 2- (aq) -------------> FeCO3 (s)

4.NaOH + AgNO3 ---------------> NaNO3 + AgOH

balanced total ionic equation = Ag+ + NO3- + Na+ + OH- ----------> Na+(aq) + NO3- (aq) + AgOH (s)

Net ionic equation = Ag+ (aq) + OH- (aq) -------------> AgOH (s)

5. FeCl2 + 2AgNO3---------------------> Fe(NO3)2 + 2AgCl

balanced total ionic equation = 2Ag+ + 2NO3- + Fe2+ + 2Cl- ----------> Fe2+(aq) + 2NO3- (aq) +2 AgCl (s)

Net ionic equation = 2Ag+ (aq) + 2Cl- (aq) -------------> 2AgCl (s)
