Sketch a heating curve graph of temperature The b. p. of methanol is 65°C and that of ethanol is 78°C.
Describe how you could use the information in the graph you sketched to separate a mixture of methanol and ethanol

Ethanol (c2h5oh) is produced from the fermentation of sucrose in the presence of enzymes. c12h22o11(aq) + h2o(g) 4 c2h5oh(l) + 4 co2(g) determine the theoretical yield and the percent yields of ethanol if 680. g sucrose undergoes fermentation and 326.5 g ethanol is obtained. theoretical _ g _ percent %
