Faraday’s Law 1. Hydrogen fuel cells are based on the reaction of hydrogen and oxygen to form water: 2H 2 (g) + O 2 (g) ? 2H 2O (l) In the presence of excess oxygen, a hydrogen fuel cell consumes 0.370 grams of hydrogen per hour at 25°C. Calculate the maximum current that can be produced by this fuel cell. 2. Aluminum is produced by the electrolytic reduction of alumina, Al 2O 3. The overall cell reaction can be written...

POGIL-Stoichiometry How do chemists use balanced chemical equations? got bit D 23 mosquitoes? 10 He got Mol-aria Why? Chemists use balanced chemical equations as a basis to calculate how much reactant is needed or product is formed in a reaction. This is called Stoichiometry- (stoi-key-ah-meh-tree) Another way of looking at it is using the mole ratio from the balanced equation and information about one compound in the reaction to determine information about another compound in the equation. A mole ratio...

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...
