1)Sodium thiosulfate is used to remove excess Cl2 from chlorine-bleached fabrics. The thiosulfate ion forms SO42− and elemental sulfur, while Cl2 is reduced to Cl−. Express your answer as a chemical equation including phases. 2) An aqueous solution of SO2 reduces aqueous KMnO4 to MnSO4(aq). Write balanced equation for this reaction. 3)An aqueous solution of SO2 reduces acidic aqueous Cr2O72− to aqueous Cr3+. Write balanced equation for this reaction.
Review Intelligent Tutoring Problem 6.65 A 1.000 mol sample of propane, a gas used for cooking in many rural areas, was placed in a bomb calorimeter with excess oxygen and ignited. The initial temperature of the calorimeter was 25.000 °C and its total heat capacity was 97.13 kJ °C-1. The reaction raised the temperature of the calorimeter to 27.282 °C. Write the balanced chemical equation for the reaction in the calorimeter. How many joules were liberated in this reaction? What...
2. A piece of sodium metal reacts completely with water as follows: 2Na(s) + 2H2O(l) à 2NaOH(aq) + H2(g). The hydrogen gas generated is collected over water at 25.0oC. The volume of the gas is 252mL measured at 1.00atm. Calculate the number of grams of sodium used in the reaction. (Vapor pressure of water at 25oC = 0.0313atm). a. 0.23g b.0.25g c. 0.474g d. 0.459g 3. Write the ground state electron configuration for Iron. a. [Kr]5s24d105p5 b. [Rn]7s1 c. 1s22s22p5...

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...
