For the electrolysis of molten chromium bromide (CrBr3) (The minimum voltage that must be applied to a cell containing molten CrBr3 in order for electrolysis to occur is 1.83V.) Cr3+ (aq) + 3 e− ⟶ Cr(s) −0.744 Br2(aq) + 2 e− ⟶ 2 Br−(aq) +1.0873 a) Identify the reaction that occurs at the anode and the cathode. b) If 3.65 V is applied for 85 minutes, what mass of Cr(s) will be produced? c) If 15.00 A of voltage is applied, how long would...

Elemental calcium is produced by the electrolysis of molten CaCl2. A) What mass of calcium can be produced by this process if a current of 6600 A is applied for 50 h? Assume that the electrolytic cell is 66 % efficient. Express your answer using two significant figures. *incorrect answer = 8.1 x 10^8 g; 8.6 x 10^8 g B) What is the minimum voltage needed to cause the electrolysis? Express your answer using three significant figures.

Molten salts When electricity is applied to a molten binary salt, the cation will be reduced and the anion will be oxidized. The electrolysis of CaBrz (), for example, produces Ca(s) at the cathode (from the reduction of Ca2+) and Br2(1) at the anode (from the oxidation of Br"). If more than one cation is present, only the one with highest reduction potential will be reduced. Similarly, if more than one anion is present, only the one with the highest...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
