A water sample is found to contain Cu but no organic or inorganic ligands except OH-. Assume that only one hydrolysis species contributes significantly to the total Cu in solution. (a) Using the soluble species in the chemical reaction below, write a mass balance expression for the concentration of total soluble Cu. (Place Cutotal on the left side of the equation.) 5 points K log Kf Cu2++H2O⇌Cu(OH)++H+{“version”:”1.1″,”math”:”Cu2++H2O⇌Cu(OH)++H+”} 10-7.52 -7.52 (b) Express Cutotal in terms of free (Cu2+) (that is, (Cu2+) should occur in all terms on the right side of the equation). 10 points Show your work to the best of your ability here, and upload an image of your scratch paper. If you cannot type out your work, be sure that it is included on the scratch paper. You can upload your scratch paper by clicking on the camera icon or by clicking Add a File. You may alternatively do the same in the show work question below. If this doesn’t work, add the image to the Exam 1 – Scratch Paper Dropbox located in the Assignments tab of this D2L site after you submit this exam.

News breаks thаt Ebоlа strikes Kikwit Africa again. This time it is the virulent strain knоwn as the Zaire strain оf Ebola. An observant physician notices that when a blood transfusion from a survivor of Ebola, they dying patient survives. The physician gets permission from a hospital administrator to run a series of tests to see if the blood transfusions are the reason the dying patient survived. Two groups of 10 patients are all given blood transfusions during their sickness. Ten patients in Group A receive 4 pints of normal blood (blood from donors that have not had Ebola). Ten patients in Group B are given 2 pints of normal blood and 2 pints of blood from Ebola survivors. All patients are then given the same antiviral medications, meals, water, and living conditions in the hospital in Kikwit. At the end of 2 weeks, 9 patients have died in Group A and only one patient from Group B dies. The results indicate that blood from Ebola survivors protects against the virus. The rate of survival in both groups would illustrate the __________________________ variable.
