If I have AgNO3 + Na2CO3 and I am asked to give the NET IONIC EQUATION - what is different than if I would just give a regular equation? Do I simply switch NO3- and CO3(2-) from one element (Ag to Na) to another? Will this be the same when mixing Pb(NO3)2 and NaCl. And mixing Sb(OH)3 and Na2S. Also - what does it mean when they say you will have a double displacement reaction?? thank you!

For a balanced net ionic equation - do I write the charge of the ion as well as add (in necessary) a coefficient in front --ex. 2Sb3+ + 3S2- ---> Sb2S3?
Or do I simply put the charges and omit the coefficients??

The net ionic equation is 2Ag+ + CO3= ===> AgcCO3(s), because that shows what's really driving the reaction. The Na+ and NO3 are called spectator ions. Similarly, Pb++ + Cl- ===> PbCl2(s) and 2Sb+++ + 3S= ===> Sb2S3(s).

Net ionic simply is a simpler equation than the double replacement that you are suggesting. Double replacement is what you were mentioning in the second sentence when you said "do i simply switch ...". In a net ionic you only write out what goes in to form the precipitate in this case. So it would be 2Ag(1+) + CO3(2-) --> Ag2CO3.
