Powdered coal ( essentially pure C ) is reacted with excess water to make a mixture of CO,CO2 and H2 The reaction is desired reaction ,CO2 is an undesired waste product. This gas mixture from the reactions of coal with water is further reacted over a catalyst to make methanol (CH3OH)
The Coal is fed with 200% excess water ( excess is calculated with respect to CO formation) 100% of coal is consumed. the selectivity to CO (with respect to CO2) is 1:1 the functional conversion of the CO is 50% what is the final gas composition ? ( all final species are in the gas phase
C+H2O = CO +H2
C+2H2O = CO2 +2H2
CO+2H2O=CH3OH+1/2 O2
captain kirk of the starship enterprise, has been told by his superiors that only a chemist can be trusted with the combination to the safe containing the dilithium crystals that power the ship.
Write balanced, net ionic equations when the following compounds are mixed. Indicated mixtures where no reaction is expected with the notation no rxn.
Kc for this reaction is 5.1 at 400 degrees C. Calculate the equilibrium concentrations of the four gases if the initial concentration of each of them is 0.050M.
The absorption spectra of ions have been used to identify the presence of the elements in the atmospheres of the sun and other stars. What is the wavelength of light (in nm) that is absorbed by He+ ions
how many moles of carbon dioxide will be formed upon the complete reaction of 0.793 moles carbon monoxide with excess water?
what is the relationship between the structure of the fabric molecule and the intensity with which the azo dyes color the fabric?
If you didn't wipe away any frost or condensation formed during sublimation, how would your molar mass value be affected? Be specific please.
A sample of gas occupies a volume of 364 mL at 1.28 atm and 27 oC. Calculate the volume of the gas if its temperature is changed to 57.0 oC while its pressure is held constant.
Acid-base titration & analytical chemistry, A 0.213-g sample of uranyl(VI)nitrate, UO2(NO3)2, is dissolved in 20.0 mL of 1.0 M H2SO4 and shaken with Zn. The zinc reduces the uranyl ion, UO2 (with a charge of 2+)
describe three distinctly different reactions of furan which confirm the relatively smaller aromatic resonance stabilization of furan compared with thiophene and pyrrole (reactions which lead to non aromatic products)
