To balance the redox reaction between copper metal and silver nitrate solution, we first need to identify the oxidation and reduction half-reactions.Oxidation half-reaction: Cu s Cu aq + 2eReduction half-reaction: Ag aq + e Ag s Now, we need to balance the electrons in both half-reactions. Since the oxidation half-reaction has 2 electrons and the reduction half-reaction has 1 electron, we will multiply the reduction half-reaction by 2 to balance the electrons:Oxidation half-reaction: Cu s Cu aq + 2eReduction half-reaction: 2Ag aq + 2e 2Ag s Now, we can combine the two half-reactions to get the balanced redox reaction:Cu s + 2Ag aq Cu aq + 2Ag s Finally, we need to include the nitrate ions to complete the reaction:Cu s + 2AgNO aq Cu NO aq + 2Ag s This is the balanced redox reaction for the reaction between copper metal and silver nitrate solution to form copper II nitrate and silver metal.
