5. (50pts) Complete the following: a. Construct a Galvanic Electrochemical Cell that has an overall voltage that ranges between 2.10 V and 2.79 V. You must label all of the parts and include all calculations to justify why you choose this cell to receive credit. Remember, there is no right or wrong choice here but how you justify your answer. b. Using your results from problem 1, construct the representative cell diagram. C. Using the electrochemical cell in problem 1,...

Using the electrochemical series and the standard reduction potential tables in your text, would you be able to form a galvanic cell using chromium and silver? If so, what would be the Ecell for the galvanic cell, what would be the overall bal anced equation, and what would be the electrolyte solutions for each half cell? (2 points total)

A fuel cell is an electrochemical device that reacts hydrogen with oxygen from the air to produce water and DC electricity. A proposed application is replacement of the gasoline-fueled internal combustion engine in an automobile with a 100 kW fuel cell. You are on a summer internship with a gas supplier planning to transport hydrogen to service stations for the use in cars powered by fuel cells. The hydrogen is to be transported in tube trailers, each of which has...

Draw your very own Galvanic cell. The process you will be using is that solid chromium releases two electrons, becoming chromium (II) ions. At the same time, iron (II) ions acquire there electrons, forming solid iron metal. Make sure you label each part of your Galvanic cell. Do not forget site of oxidation, site of reduction, porous plug, wire, salt bridge, anode, cathode. Indicate the metal at each site and the resulting movement of ions.

Assume that you have an app on your cell phone that allows you to walk up to any item in the supermarket, have your phone recognize it, and then display all the necessaey information about the product. Imagine that the app even tells you where and how it is made, and when it is predicted to go on sale next. This app would mean that a firm selling goods in this setting would (A - still need to advertise or...
