How many liters of sulfur dioxide, measured at STP, are produced by the reaction of 4.55 kg of galena with 199 L of oxygen gas at 220°C and 2.00 atm? Lead(II) oxide also forms. 162. 3 L SO2
An environmental engineer is sampling the stack gas produced by a coal-burning power plant. The stack gas (a mixture of carbon dioxide, sulfur dioxide, and water) is pumped into a 20.0 liter cylinder at a pressure of 1.20 atm, and a temperature of 325 K. It is determined that the sample contains 0.315 mol of C02 and 0.494 mol of H20 a) How many moles of sulfur dioxide were present in the sample? b) What is the partial pressure (in...
When solid lead(II) sulfide reacts with oxygen gas, the products are solid lead(II) oxide and sulfur dioxide gas. A. Write the balanced equation for the reaction. Express your answer as a chemical equation. Identify all of the phases in your answer. B. How many grams of oxygen are required to react with 25.3 g of lead(II) sulfide? C. How many grams of sulfur dioxide can be produced when 56.8 g of lead(II) sulfide reacts? D. How many grams of lead(II)...
Enter your answer in the provided box. Consider the formation of nitrogen dioxide from nitric oxide and oxygen: 2 NO(g) + O2(g) +2 NO2) If 5.39 L of NO is combined with excess O2 at STP, what is the volume in liters of the NO2 produced? L
Enter your answer in the provided box. When coal is burned, the sulfur present in coal is converted to sulfur dioxide (SO2), which is responsible for the acid rain phenomenon: Ss) + O2(g) → SO2(9) If 3.15 kg of S reacts with oxygen, calculate the volume of So, gas (in mL) formed at 30.5°C and 1.04 atm.
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...
