Yes, I'm sure many people know the net ionic equations. But rather than provide them all to you, how about we just do a couple so you can do the rest.
Here is a general outline for doing this:
-Write the compete balanced molecular equation including phases
-Write the total ionic by ionizing/dissociating those than can be (strong electrolytes, etc.) leaving solids, liquids gases and weak electrolytes as is
-Cancel spectator ions from each side and write the net ionic equation
1). Li2SO4(aq) + Ca(NO3)2(aq) ==> 2LiNO3(aq) + CaSO4(s) ... molecular equation
2Li+(aq) + SO42-(aq) + Ca2+(aq) + 2NO3-(aq) => 2Li+(aq) + 2NO3-(aq) + CaSO4(s) ... total ionic
Ca2+(aq) + SO42-(aq) ==> CaSO4(s) ... net ionic
3). AlCl3(aq) + 3NaOH(aq) ==> Al(OH)3(s) + 3NaCl(aq) ... molecular equation
Al3+(aq) + 3Cl-(aq) + 3Na+(aq) + 3OH-(aq) ==> Al(OH)3(aq) + 3Na+(aq) + 3Cl-(aq) ... total ionic
Al3+(aq) + 3OH-(aq) ==> Al(OH)3(s) ... net ionic
5. Solutions of aqueous potassium iodide and aqueous calcium nitrate are mixed.
Mixing solutions of potassium iodide and calcium nitrate would not result in a chemical reaction because all compounds are soluble and so there is not net ionic equation. All would be spectator ions.
KI(aq) + Ca(NO3)2 ==> 2KNO3(aq) + CaI2(aq) NO REACTION
6. A reaction occurs between aqueous ammonium phosphate and aqueous barium hydroxide.
When solutions of ammonium phosphate and barium hydroxide are mixed, this results in the formation of insoluble barium phosphate and soluble ammonium hydroxide.
2(NH4)3PO4(aq) + 3Ba(OH)2(aq) ==> Ba3(PO4)2(s) + 6NH4OH ... balanced formula equation
