Question 3 An ideal gas mixture consists of 25 percent hydrogen, 50 oxygen, and 25 carbon monoxide, based on mass. Perform a volumetric analysis to determine the molecular weight of the mixture, in kg/kmol. Question 4 A mixture of 0.6 iso-octane and 0.4 methanol, based on weight, is combined with air and combusted. Calculate the stoichiometric air fuel ratio.

Hydrogen and oxygen gases are utilized as reactants for fuel cells. Hydrogen gas is oxid side to generate protons and electrons which move to the cathode side to react with oxygen to produce electricity and water as byproduct. Molecular weight: M(H2) -2 g/mol, M(O)-32 g/mol, M(H-0) - 18 g/mol. Detailed reactions in each side are described below: ized in the anode (-) side: | (+) side: Cell: H2 → 2H+ + 2e- E" 0.00V 202 + 2H+ + 2e-→ H2O...

Quantitative: In the 1950s liquid hydrogen was considered as a fuel for a new type of aircraft being developed, the SR-71 Blackbird (shown in Figure 1). Figure 1: The SR-71 Blackbird Early research on the project focused on which fuel to use for the Blackbird. Pratt & Whitney had a J-57 engine that was designed for kerosene and being considered for implementation on the Blackbird. The J-57 only took 5 months to convert to running on liquid hydrogen, however tests...

1. When sodium metal is dropped into liquid water, the mixture releases gaseous hydrogen. leaving behind a colorless solution of sodium hydroxide. Balance the equation that represents this reaction. 2. Liquid butane is often used as a fuel in cigarette ligthers. When the pressure is released, butane evaporates and can burn with oxygen. Balance the following skeletal equation for the reaction of butane with oxygen gas. O p +Os c Op+H:0 3. Balance the following equation: Zn + HNO- Zn(NO...

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...
