Titleabc123 Version X1week 4 Exerciseschm109 Version 21university Of Prepare written answers to the following exercises: 1. Imagine that you are an environmental scientist. Working in collaboration with a university chemist, you were able to determine from mass spectrometry that four elements exist in your soil samples. They are Se, Sn, Pb, and Cd. You need to determine which elements will most likely combine with oxygen to produce oxides that are present in your sample. To do so, refer to the periodic table to determine the electron configuration and ionization energy of each element. This will show the number of valence electrons for each element. What are the electron configurations for Se, Sn, Pb, and Cd? What are the valence electrons for Se, Sn, Pb, and Cd? Rank the elements in increasing ionization energy. Which element will form oxides? 2. Imagine that, as an employee of a pharmaceutical company, you are working on an H-K-ATPase. It is the enzyme that pumps acid into the stomach to help in digestion. You are trying to determine whether a compound will fit inside the pocket of this enzyme in order to inhibit the enzyme. To do so, you must know the molecular shape of the compound. Draw the Lewis structure and determine the molecular geometry of the following compounds that may fit into the active site of this enzyme: · CO2 · KOH · NO3 · HCN 3. Imagine that you work as a chemist in a battery manufacturing plant. You are asked to try a variety of substances that can be used to generate an ion potential necessary to produce electricity. Ionic compounds produce ions that can generate an ion potential when placed in an aqueous solution. Name the various compounds in the following table and label them as ionic or molecular: Formula Name Ionic or molecular PtO2 CF2Cl2 CO KClO3 CoSO4 CO2 SO3 Ba(NO3)2 NH4I NaClO4 decide whether you would like to study "Chemistry in Medicine" or "Chemistry in the Environment."

 Link Seven Reading: You may focus your reading on EITHER the "chemistry in medicine" links OR the "chemistry in the environment" links. Whichever category you choose, please read the websites under that category carefully! Please select which of these two topics you would like to study, read the links related to that topic. 1. Decide whether you wish to study "chemistry in medicine" or "chemistry in the environment". 2. Post a one-paragraph summary of the link/article of your choosing from the options listed below within whichever category you decide (related to your selected topic). 3. Post a one-paragraph summary of a related link/topic that is NOT listed as one of the links below - this will need to be a website or article that you find on your own. Please
