Need help making chemical formulas for each of these reactions!!!?

Question

All of these do react I just need help writing the formulas. You don't have to do all of them any would help. The part I'm having trouble with is making sure the equations are balanced. (KI is k and i not L and Cl is c and L)

AgNO3 + KI --->
AgNO3 + NaCl --->
AgNO3 + NaOH --->
AgNO3 + FeCl3 --->
AgNO3 + Na2CO3 --->
Pb(NO3) 2 + KI --->
Pb(NO3) 2 + NaCl --->
Pb(NO3) 2 + NaOH --->
Pb(NO3) 2 + K2SO4 --->
Pb(NO3) 2 + ZnSO4 --->
Pb(NO3) 2 + Na2CO3 --->
Pb(NO3) 2 + CuSO4 --->
BaCl2 + NaCl --->
BaCl2 + K2SO4 --->
BaCl2 + ZnSO4 --->
BaCl2 + Na2CO3 --->
BaCl2+ CuSO4 --->

Answer 1

For most of these, you're just doing a swap between anion and cation.

For AgNO3 and Pb(NO3)2 , remember that NO3 has a charge of -1. That should help you do all of them:
AgNO3 + KI ---> AgI + KNO3

For sulfates, SO4 has a charge of 2-:
Pb(NO3)2 + ZnSO4 ---> PbSO4 + Zn(NO3)2

And for carbonates, Co3 has a charge of 2-:
BaCl2 + Na2CO3 ---> BaCO3 + 2 NaCl
