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.
Arrange the subsequent aqueous solutions in order of increasing freezing points (lowest to highest temperature): 0.10m glucose,0.10m BaCl2 , 0.20m NaCl and 0.20mNa2SO4
