Use the stаndаrd hаlf-cell pоtentials listed belоw tо calculate the standard cell potential for the following reaction occurring in an electrochemical cell at 25°C. (The equation is balanced.) Sn(s) + 2 Ag⁺(aq) → Sn2+(aq) + 2 Ag(s)Sn2+(aq) + 2 e⁻ → Sn(s) E° = -0.14 VAg⁺(aq) + e⁻ → Ag(s) E° = +0.80 V
