Formulate the equations of the stoichiometric coefficients for stoichiometriccombustion (in air) of a generic fuel CxHyOz, where x, y, and z may be any non-negative integer for pure fuels, or non-negative real numbers for fuel blends. Also, formulate the equations for the mixture molecular mass, mole factions, andmass fractions of the combustion products H2O, CO2, and N2 and the fuel-to-airratio. Using the formulations, compute the stoichiometric coefficients, mixturemolecular mass, mole factions, and mass fractions for methane (CH4) and bio-diesel (C19H36O2) fuels. Repeat problem for ethanol (C2H6O), and gasoline (C8H15.6).

Stage in which a star’s outer layers have started to cool and grow outward?

One way in which the useful metal copper is produced is by dissolving the mineral azurite, which contains copper(ii) carbonate, in concentrated sulfuric acid. the sulfuric acid reacts with the copper(ii) carbonate to produce a blue solution of copper(ii) sulfate. scrap iron is then added to this solution, and pure copper metal precipitates out because of the following chemical reaction: (s) (aq) (s) (aq) suppose an industrial quality-control chemist analyzes a sample from a copper processing plant in the following way. he adds powdered iron to a copper(ii) sulfate sample from the plant until no more copper will precipitate. he then washes, dries, and weighs the precipitate, and finds that it has a mass of .
