text: write the ionic equation for the following reactions: 2agno3(aq)+na2so4(aq) produces ag2so4(s)+2nano3(aq)? ag has a 1+ charge, no3 has a 1- charge, na has a 1+ charge and so4 a 2- charge.  i understand that but i cannot seem to get the problem right. 2ag+ 2no3- + 2na+ + so4(2-) --> ag2so4+ 2na+ + 2no3-
