What will be the the net ionic equations for the following ones: - a) agno3 + kcl b) ni(no3)2 + na2s c) cacl2 + na2co3. 2) write out the total ionic equation and cancel anything that is common on both sides ca+2(aq) + 2cl-(aq) + 2na+(aq) + co3-2(aq) --> caco3(s) + 2na+(aq) + 2cl-(aq)

The molecular equation is

AgNO3(aq]+HCl(aq]→AgCl(s]+HNO3(aq]

How did I get this equation? Consider each reactant or product separately:

1 mole of AgNO3 contains 1 mole of Ag+ and 1 mole of NO−3 ions.

Ag+(aq]+NO−3(aq]+H+(aq]+Cl−(aq]→AgCl(s]⏐⏐↓+H+(aq]+NO−3(aq]

The net ionic equation is

Ag+(aq]+Cl−(aq]→AgCl(s]⏐⏐↓

Now try some of the others on your own
