Copy down the potential from the diagram above, as shown on the voltmeter: ___1.10_______ V Note: Voltage (V) is a measurement of the electrochemical potential or “electromotive force” (e.m.f.), how charged particles are being pushed in one direction or another. In the case of the copper/zinc electrochemical battery, the 1.10 V means that each Coulomb (C) of electric charge will gain an energy of 1.10 Joule (J) (1 V = 1 J/C). For reference, 1 electron has a charge of 1.602 x 10-19 C (or 1 mole of electrons carry about 100,000 C of electric carge).The common data of electrochemical potential is in the form of standard reduction potential tables, like the one shown below (similar to Table 17.1 in OpenStax): ****Note that the reduction of H+ to become H2 is set as 0.00 V. The electrode made of this combination is called the standard hydrogen electrode (SHE), and standard reduction data is usually presented with respect to SHE. One intuitive way to understand the standard reduction table…
hello i am having difficulty with this question. last answer you provided was wrong. handwritten solutions are prefered.

Question: Do you expect ∆S° for the dissolution of borax to be a positive or negative number? Explain your reasoning.
Table 17-1 lists common half-reactions along with the standard reduction potential associated with each half-reaction. These standard reduction potentials are all relative to some standard. What is the standard (zero point)? lf is positive for a half-reaction, what does it mean? If is negative for a half-reaction, what does it mean? Which species in Table 17-1 is most easily reduced? Least easily reduced? The reverse of the half-reactions in Table 17-1 are the oxidation half-reactions. How are standard oxidation potentials determined? In Table 17-1, which species is the best reducing agent? The worst reducing agent? To determine the standard cell potential for a redox reaction, the standard reduction potential is added to the standard oxidation potential. What must be true about this sum if the cell is to be spontaneous (produce a galvanic cell)? Standard reduction and oxidation potentials are intensive. What does this mean? Summarize how line notation is used to describe galvanic cells.
