1. The problem statement, all variables and given/known data 2AgNO3(aq) + CuCL2(aq) --> 2AgCl(s) + Cu(NO3)2(aq) The concentration of Ag(NO3)2(aq) at t = 30s is .42 mol/L. At t = 60.0 its concentration is .28 mol/L. What is the change in [CL^-] during this time? 2. Relevant equations 3. The attempt at a solution Not really sure even how to begin.
