Suppose that brown coal from a certain mine is 80.0 percent carbon by mass and the remainder is inert material. The coal is removed at a rate of 5000. kg/hour. The coal is burned to produce electricity. How many kg and moles CO2, agreenhouse has, are produced from the coal that is mined during one 8 hour shift?

1 - Mass balance
with reaction
a) A certain amount of Pennsylvania coal, in a final analysis
(by mass), has 84.36% C, 89% H2, 4.40% O2, 0.63% N2, 0.89% S and
7.83% ash (non-combustible). This coal is burned with a theoretical
amount of air. Disregarding the ash content, determine the molar
fractions of the products.

Recall the demonstration from lecture where we "burned" ethanol in a 2-gallon drum to produce carbon dioxide and water. The unbalanced equation is: C2H5OH(g) + O2(g) → CO2(g) + H2O(l) If 2.00g of ethanol reacts with 10.0g of oxygen, how many moles of carbon dioxide and how many moles of water are produced? What is the total volume of gas present (in L) after the reaction is complete assuming the reaction takes place at 1.00 atm and 25°C? Prove that...

Answer question 1g. Show the workings clearly.
Suppose a chlor-alkali plant has 250 cells, through each of which a current of 100,000A passes continuously (a) Calculate the mass of chlorine that this plant can produce per 24-hours day (b) If the cell voltage is 3.5v, calculate the total electrical energy consumed by the plant in one 24-hour day, and express it, both in Joules and in kilowatt hour, calculate the cost for the needed electricity needed to run the plant...

1. Moles of Reactant to Mass of Reactant: Identify the iodide ions and ozone in the balanced chemical equation. Use mole ratio, then convert to grams. A method used by the EPA for determining the ozone concentration in the air is to pass an air sample through a bubbler containing iodide ions. The iodide ions remove the ozone according to the following reaction: O3(g) + 2 I-(aq) + H2O(l) → O2(g) + I2(aq) + 2 OH-(aq) How many grams of ozone...

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...
