Acetaldehyde is produced by the dehydrogenation of ethanol according to the following reaction: C2H5OH CH3CHO + H2 An undesired side reaction occurs, which produces ethyl acetate: 2C2H5OH CH3COOC2H5 + 2H2 In a pilot plant, the conversion of ethanol is 90% and the yield of acetaldehyde is 58.5%. The ethanol enters the reactor as a vapor at 300°C and 5 bar pressure, and at a flow rate of 100 mol/h. How much heat must be added/removed (state which) to maintain the reactor outlet temperature at 300°C? State your answer in kJ/h.
If the titration required 23.95 mL of 0.2556 M HCl to reach the endpoint, calculate the equilibrium molar concentration of B4O5(OH)4 2- in the saturated solution.
Thomas Jefferson Snodgrass found an unlabelled reagent bottle in his -80 C freezer. The Bottle contained a liquid. He found that the compound( compound 1) quickly evaporated when warmed to room temperature. H-NMR of the compound showed only two pe..
