Animation-Analysis of Copper-Zinc Voltaic Cell Zinc Some oxidation-reduction reactions are spontaneous, and the energy released by them can be used for electrical work. This principle is used in the working of a voltaic cell. Voltaic cells, or electrochemical cells, make use of the electrons that are transferred from the species that releases electrons and undergoes oxidation to the species that accepts electrons and undergoes reduction. If it is possible by any means to separate the oxidation reaction and the reduction reaction and then connect them externally so that the electrons flow from one compartment to the other, you can construct an electrochemical cell. Watch the video that describes the cell reaction and the cell components of a voltaic cell. 1.10 14 of 42 Na₂SO₂(aq) Review | Constants | Periodic Table Z 5042 Cu2+ $0,² In a copper-zinc voltaic cell, one half-cell consists of a Zn electrode inserted in a solution of zinc sulfate and the other half-cell consists of a Cu…
Can someone please help with question 11
Answer the following questions. Write 3 redox reactions and explain them in terms of loss and gain of electrons and the associated change in oxidation number. Also witha DIAGRAM identify the components of a galvanic cell, and how each component functions in a redox reaction?

thank you, i have one more
2. Tell whether each of these statements are true and false. If false, rewite it to make it a correct statement. Oxidation always occurs at the anode of an electrochemical cell. The anode of a voltaic cell is the ite of reduction and is negative. Standard conditions for electrochemical cells are a concentration of 1.0 M for disolved species and a pressure of 1 bar for gases. The potential of a voltaic cell does not change with temperature. All product-favored oxidation-reduction reactions have a standard cell voltage E°cell, with a negative sign.
(iv) raised from 25 °C to 100 °C? Which of the following would result for any cell if the temperature was A. The cell potential would not change at all B. The cell potential would increase slightly C. The cell potential would decrease slightly D. It is impossible to determine. E. It would depend on the nature of the electrodes used.
