In the anaerobic fermentation of grain, the yeast (saccharomyces cerevisiae) digests glucose from plants to form the products glucose from plants to form the products ethanol and propenoic acid by the following overall reactions:
C6H12O6 -> 2C2H5OH + 2CO2C6H12O6 -> 2 C2H3CO2H+ 2H2O In an open, flow reactor 3500 kg of a 12% glucose/water solution flow in. During fermentation, 120 kg of carbon dioxide are produced together with 90 kg of unreacted glucose. What are the weight percents of at the alcohol and propenoic acid that exit in the broth? Assume that none of the glucose is assimilated into the bacteria.
Problem- What hydrogen ion concentration should be required to dissolve 0.10 M MgF2 if the Ksp for magnesium flouride is 6.8*10^-9and Ka for HF is 6.5*10^-4
What is the mole percent of ethanol C2H5OH which consists of 71.0g of ethanol for every 18.3grams of water present
1. 1.25 moles of nocl were placed in a 2.50 l reactionchamber at 427ordmc. after equilibrium was reached 1.10 moles of
an empty vial has a mass of 67.77 g. if the vial has a mass of 244.56 g when completely filled with liquid carbon
Calculate the percent composition and determine the molecular formula and the empirical formula for the carbon-hydrogen-oxygen compound that results when 30.21 g of carbon, 40.24 g of oxygen, and 5.08 g of hydrogen are reacted to produce a product..
Scrubbers use aqueous slurries of calcium hydroxide to remove the SO2 from flue gases. Write a balanced equation for this reaction
What is the molarity of your HCl solution if it take 35.25 mL to reach the second equivalence point of a titration against 0.2225 grams of standard sodium carbonate?
What volume of 0.200M HCl must be added to 250.0mL of 0.300M sodium mandelate to produce a buffer solution with a pH of 3.37. The answer is 194 mL of HCl; however, I'm not sure of how to solve for it.
