Suppose you have the following reagents available under standard conditions. (i.e., P = 1 atm for all gases; t = 25 oC; C = 1 mol L?1 for all aqueous species, including H+.) Co(s), Ag+(aq), Cl?(aq), Cr(s), BrO3?(aq), I2(s), F?(aq) Consult the standard reduction potentials on the next page and then answer the following questions. (a) Which is the strongest oxidizing agent? (b) Which is the strongest reducing agent? (c) Which of the available reagent(s), if any, will oxidize Fe(s) while leaving Cu(s) unreacted? If none of the available reagents can be used for this purpose, then identify another reagent from the table that could be used. For each reagent you've identified, write down a balanced chemical equation for the reaction that occurs.
While resting, the average human male consumes 200 mL of oxygen per hour at 25 degrees Calcius and 1.00 atm for each kilogram of weight. The number of moles of oxygen are unknown and if the oxygen is consumed by a 70.0 kilogram man while resting f..
A galvanic (voltaic) cell consists of an electrode composed of nickel in a 1.0 M nickel(II) ion solution and another electrode composed of copper in a 1.0 M copper(I) ion solution, connected by a salt bridge. Calculate the standard potential for t..
