The United States nickel contains about 25% nickel metal and 75% copper metal. Could you use the same experimental procedure to determine the percentage of copper metal in a nickel coin that you used for a penny? Why or why not? Describe any modifications to the procedure that would be required. Hint: think about the reactions involved and the complex ions that would be formed. Here's kind of a summary of the procedure if it helps in answering this question:...

You wish to prevent the iron in your car from rusting by installing a sacrificial anode. (Assume rust contains Fe 2+ ion.) If you had blocks of copper, palladium, or zinc, which metal would make the best sacrificial anonde? Briefly defend your answer.

The redox reaction within the PDMS has also been used to produce gold and silver nanoparticles from ionic species, but not nickel or iron nanoparticles from their metal ions. Would you expect PDMS to be used to produce zinc nanoparticles from zinc(II) ions? Why or why not?

7) One method for removal of metal ions from a solution is to convert the metal ion (M"* to its elemental form (M) so it can be filtered out as a solid. Which of the following metals can be used to remove aluminum ions (AP") from solution? A) Zinc B) Cobalt C) Lead D) Magnesium B) Copper

= O STOICHIOMETRY Solving for a reactant in solution One way in which the useful metal copper is produced is by dissolving the mineral azurite, which contains copper(II) carbonate, in concentrated sulfuric acid. The sulfuric acid reacts with the copper(II) carbonate to produce a blue solution of copper(II) sulfate. Scrap iron is then added to this solution, and pure copper metal precipitates out because of the following chemical reaction: Fe(s) + CuSO4(aq) + Cu(s) + FeSO4(aq) Suppose an industrial quality-control...
