1. The problem statement, all variables and given/known data I have got a battery with two half cells. One cell with. A silver rod in a 100 mL AgNO3 0,025 M solution. One cell with. A zinc rod in a 100 mL Zn(NO3)2 0,150 M solution. So my question is what reactions happen? And which reaction is the electricity providing one? 2. Relevant equations I do not think that there are any 3. The attempt at a solution My bet First cell (with Ag) Ag+ + NO3- + e- -> Ag + NO3- Second cell (with Zn) Zn(NO3)2 -> Zn2+ NO32- but then where are the electrons? Furthermore I think this is the electricity providing one!
