Oh, chemistry! The land of mysterious reactions and equations. Alright, let's dive into these equations and find the net ionic equations, shall we?

1. Silver(I) nitrate (AgNO3) and manganese(II) chloride (MnCl2) react. I wonder what mischief they'll create. Well, the net ionic equation would be Ag+ + 2 Cl- --> AgCl. Hey presto! Silver chloride is formed!

2. Now, we have cobalt(II) sulfate (CoSO4) and lead(II) nitrate (Pb(NO3)2, getting together for a chemical party. What happens next? Well, the net ionic equation would be Co2+ + 2 NO3- --> Co(NO3)2. Oh, lovely cobalt nitrate!

3. Finally, we mix zinc nitrate (Zn(NO3)2) and sodium sulfate (Na2SO4). What kind of chemistry magic will we witness here? The net ionic equation is Zn2+ + SO4(2-) --> ZnSO4. Ah, poetic zinc sulfate, the result of this reaction.

Voilà! I hope I've added a touch of humor to these equations. Let me know if there's anything else I can help you with!

To determine the net ionic equations for these reactions, we need to start by writing the balanced molecular equations, followed by the complete ionic equations, and finally, the net ionic equations.

1. Reaction between silver(I) nitrate and manganese(II) chloride:
Molecular equation: AgNO3(aq) + MnCl2(aq) → AgCl(s) + MnNO3(aq)

Complete ionic equation:
Ag+(aq) + NO3-(aq) + Mn2+(aq) + 2Cl-(aq) → AgCl(s) + Mn2+(aq) + NO3-(aq)

Net ionic equation:
Ag+(aq) + 2Cl-(aq) → AgCl(s)

2. Reaction between cobalt(II) sulfate and lead(II) nitrate:
Molecular equation: CoSO4(aq) + Pb(NO3)2(aq) → PbSO4(s) + Co(NO3)2(aq)

Complete ionic equation:
Co2+(aq) + SO4^2-(aq) + Pb2+(aq) + 2NO3-(aq) → PbSO4(s) + Co2+(aq) + 2NO3-(aq)

Net ionic equation:
Co2+(aq) + SO4^2-(aq) → CoSO4(s)

3. Reaction between zinc nitrate and sodium sulfate:
Molecular equation: Zn(NO3)2(aq) + Na2SO4(aq) → ZnSO4(s) + 2NaNO3(aq)

Complete ionic equation:
Zn2+(aq) + 2NO3-(aq) + 2Na+(aq) + SO4^2-(aq) → ZnSO4(s) + 2Na+(aq) + 2NO3-(aq)

Net ionic equation:
Zn2+(aq) + SO4^2-(aq) → ZnSO4(s)

These are the net ionic equations for the given reactions.

To determine the net ionic equations for these reactions, we need to first write the balanced molecular equation, followed by the complete ionic equation, and finally, identify and cancel out the spectator ions to obtain the net ionic equation.

1. Reaction between aqueous solutions of silver(I) nitrate and manganese(II) chloride:
The balanced molecular equation is: AgNO3(aq) + MnCl2(aq) → AgCl(s) + Mn(NO3)2(aq)
To write the complete ionic equation, we split all aqueous compounds into their constituent ions: Ag+(aq) + NO3-(aq) + Mn2+(aq) + 2Cl-(aq) → AgCl(s) + Mn2+(aq) + 2NO3-(aq)
Now, let's identify the spectator ions. In this case, Mn2+ and NO3- are spectator ions because they appear on both sides of the equation unchanged. Therefore, they can be canceled out. The net ionic equation is:
Ag+(aq) + Cl-(aq) → AgCl(s)

2. Reaction when aqueous solutions of cobalt(II) sulfate and lead(II) nitrate are combined:
The balanced molecular equation is: CoSO4(aq) + Pb(NO3)2(aq) → PbSO4(s) + Co(NO3)2(aq)
The complete ionic equation is: Co2+(aq) + SO4^2-(aq) + Pb2+(aq) + 2NO3-(aq) → PbSO4(s) + Co2+(aq) + 2NO3-(aq)
In this case, Co2+ and NO3- are the spectator ions since they are present on both sides. Canceling them gives us the net ionic equation:
SO4^2-(aq) + Pb2+(aq) → PbSO4(s)

3. Reaction between aqueous solutions of zinc nitrate and sodium sulfate:
The balanced molecular equation is: Zn(NO3)2(aq) + Na2SO4(aq) → ZnSO4(aq) + 2NaNO3(aq)
The complete ionic equation is: Zn2+(aq) + 2NO3-(aq) + 2Na+(aq) + SO4^2-(aq) → ZnSO4(aq) + 2Na+(aq) + 2NO3-(aq)
Here, Na+ and NO3- are the spectator ions as they are present on both sides. The net ionic equation is:
Zn2+(aq) + SO4^2-(aq) → ZnSO4(aq)

By following these steps, we can obtain the net ionic equations for various chemical reactions involving aqueous solutions.

I'll do one and the others are yours.

There are several steps to this.
1. Write and balance the molecular equation.
2AgNO3(aq) + MnCl2(aq) ==> 2AgCl(s) + Mn(NO3)2(aq)

2. Convert the molecular equation into a total ionic equation. The following rules apply.
a. Salts soluble in water are written as separate ions.
b. Gases are written as a molecule.
c. Solids are written as a molecule (as AgCl is done above). Look on the web or your notes to find a set of solubility tables that will tell you what compounds are insoluble.
d. Weak electrolytes (those with a Ka value) are written as compounds.
2Ag^+(aq) + 2NO3^-(aq) + Mn^2+(aq) + 2Cl^-(aq) ==> 2AgCl(s) + Mn^2+(aq) + 2NO3^-(aq)

3. Cancel those ions common to both sides
In the example above, You have 2NO3^-(aq) on both sides so cancel them. You have Mn^2+(aq) on both sides so cancel them.

4. What's left is the net ionic equation. That is
2Ag^+(aq) + 2Cl^-(aq) ==> 2AgCl(s)

I'll be glad to explain or embellish anything above. The second problem above is the same kind. Be carefule with the third; that one is a little tricky.
