when the oxidation-reduction reaction shown here is balanced, how many electrons are transferred for each atom of copper that reacts? When the oxidation-reduction reaction shown here is balanced, how many electrons are transferred for each atom of copper that reacts? Ag (aq) + Cu(s) → Ag(s) + Cu2(aq) a. 1 c. 3 e. 0 b. 2 d. 4
AGº and Eº can be said to measure the same thing, and are convertible by the equation AG° = -nFE cell where n is the total number of moles of electrons being transferred, and F is the Faraday constant 9.64853415 x 104 C/mol. The free energy (AGC) of a spontaneous reaction is always negative. For each of the electrochemical cells below, calculate the free energy of the system and state whether the reaction is spontaneous or non- spontaneous as written...

Chemical equations of reduction–oxidation (redox) reactions can be quite nontrivial to balance. To do so, you begin with balancing the number of electrons some particles lose in oxidation and other particles gain in reduction. Consider a reaction between potassium permanganateKMnO4 andhydrochloricacidHCl(aq), which can be used in a lab to produce chlorine gas Cl2. In this reaction, a MnO− 4 ion is reduced to a Mn2+ ion by getting electrons from Cl− and losing its oxygen atoms to bind with H+...
