Explanation / Answer

1.)

Molecular Equation:

2NaCl(aq) + Ca(NO3)2(aq) -> 2NaNO3(aq) - + CaCl2(aq) -

Complete ionic Equation:

2 Na(1+)(aq) - + 2Cl(1-)(aq) - + Ca(2+)(aq) + (NO3)2(2-) -> 2 Na(1+)(aq) - + NO3(1-) (aq) - + Ca(2+) Cl2 (2-)(s)

Net ionic equation:

Ca(2+) (aq) +   2Cl(1-) (aq) -----> CaCl2(s)

2.)

AgNo3 + NaCl => AgCl + NaNo3 is the simplified reaction

In aqueous solution you will have ions

Complete ionic Equation:

Ag+(aq) - + No3-(aq) + Na+(aq) + Cl-(aq) => AgCl(s) + Na+ No3-(aq)

Net ionic reaction:

Ag+(aq) + Cl- (aq) --------> AgCl(s) (ppt.)

The silver chloride, being essentially insoluble, precipitates out as a solid

3.)

molecular equation:

Pb(NO3)2(aq) + 2KI(aq) ----> PbI2(s) + 2KNO3(aq)

In aqueous solutions (aq) the compounds are all dissociated into their constituent ions. The Comp[lete ionic equation shows all the ions present in solution seperately.

Complete ionic Equation:

Pb2+(aq) + 2NO3(-)(aq) + 2K+(aq) + 2I-(aq) --> PbI2(s) + 2K+(aq) + 2NO3(-)(aq)

When you look at the abouve equation you can see that the 2NO3(-)(aq) and the 2K+(aq) are the same on both sides of the equation. This means they are not participating in the reaction, they are spectator ions. The NET ionic equation shows only those species in a reaction that are actually reacting. The spectator ions are left out.

NET ionic equation:

Pb2+(aq) + 2I-(aq) = PbI2(s)

4.)

Molecular Equation:

:   Na2CO3(aq) + 2KNO3 (aq) -----> 2NaNO3 (aq) + K2CO3 (aq)

Complete ionic Equation:

2 Na+(aq) + CO32-(aq) + 2K+(aq) + 2NO3-(aq) ----------> 2Na+(aq)   +   2NO3- (aq) + 2K+(aq) + CO32-(aq)  

Net ionic equation:

2K+(aq) +    CO32-(aq) ------>    K2CO3 (s)

5.)

Balanced Formual equation:

NaOH(aq) + HCl(aq) ------> NaCl(s) + H2O(l)

Complete ionic reaction:

  Na+(aq) + OH-(aq) + H+(aq) + Cl-(aq) --------> Na+(aq) + Cl-(aq) + H20 (l)

Net Ionic Equation:

H+(aq) (+) OH-(aq) -----------------> H2O (l)

6.)

Molecular Equation:

Na2CO3(aq) + BaCl2(aq) --> BaCO3(s) + 2NaCl(aq)

The barium ions from the barium chloride will combine with the carbonate ions from the sodium carbonate to make insoluble barium carbonate, leaving sodium ions and chloride ions in solution, since NaCl is soluble in water.

Complete onic equation:

2Na+(aq) + CO3^2-(aq) + Ba2+(aq) + 2Cl-(aq) --> BaCO3(s) + 2Na+(aq) + 2Cl-(aq)

We write only the BaCO3 as a compound, and not ions, since it is insoluble in water, and not dissociated.

Net ionic equation:
Ba2+(aq) + CO3^2-(aq) --> BaCO3(s)

7.)

NaOH is a strong base, so it separates. Acetic acid is really weak so it remains as whole. NaCH3COO(aq) separates because it is a salt.

Complete ionic reaction:

CH3COOH(aq) + Na^+ + OH^- ---> Na^+ + CH3COO^- + H2O

Na cancels
net ionic equation:

CH3COOH(aq) + OH^-(aq) ---> CH3COO^-(aq) + H2O(l)
