1. The problem statement, all variables and given/known data
So the question is:
Enter the net ionic equation for the reaction of aqueous sodium chloride with aqueous silver nitrate.
2. Relevant equations
So i know that the first part of the equation is:
Na(ClO2)aq+Ag(NO3)aq --> i have no clue what should go here.
Please help
3. The attempt at a solution
and i dont ebern know how to attempt this problem.... i tried:
Ag(aq) --> (ClO2)s
because this is what would change but it is saying it is not right.

NaClO2 is not sodium chloride.
Start writing both compounds in ionic form, the way they dissociate in the solution. Don't ignore charges.

OH WAIT!!!! Sodium Chloride is just NaCl.
So it would be:
Na++Cl++Ag+NO3-
Close, just add correct charge to Ag.
Do you have any idea what can happen when you mix these salts? Hint: answer lies in the solubility rules.

The Charge on Ag is a + right but my professor said something about in the Net ionic equation how all the reactents are not in it. so i was wondering how i would write the end equation.... would it be:
Ag+(aq) --> Cl-(s) or something like that..
Try to answer my question: what will happen in the solution?

the soluble ployatomic ion NO3 would attach to the Na and the Ag would attach to the Cl and the AgCl would become a solid while the Na(NO3) would still be aq... right?
Yes and no. You are right about AgCl precipitating from the solution and becoming solid, you are wrong about NO3- attaching to Na+ - they will just float in the solution, they aren't called spectators without a reason.
Now you should be able to write full ionic equation and cancel out spectators.
