NOTE: Since there are many subparts in the question and it is not possible to complete all of them in one given time interval, I am solving first three. Please repost the question for rest of the answers. Electrochemistry is study of movements of electrons from an electrolyte to generate electricity. The half-cell of reactions is when a cell has two parts one is the anode where oxidation takes place and other is the cathode where reduction takes place. The cell potential can be calculated by the following formula Ecell°=E°red- E°oxda). The diagram of voltaic cell with anode, cathode and flow direction of electrons can be shown as: b). The balance chemical reaction is 2Sn(s)+ Ag(aq)+→ Sn(aq)2+ + Ag(s) c). From the reaction above, Oxidation is seen in Sn and reduction is seen in Ag Eoxd°=0.15 VEred°=0.799 VEcell°=E°red- E°oxd=0.799-0.15=0.649 V
