At 50 degrees C calculate the vapor pressure of a solution prepared by dissolving 0.030 moles of glucose, C6H12O6 in 100. g of water. The vapor pressure of water at 50 degrees C is 345 Torr.
Rank the following solvents in order of increasing polarity: Acetone, Petroleum ether, methanol, ethanol, dichloromethane
Assuming that a chemical reactions doubles in rate for each 10 C Temperature increase, by what factor would the rate increase
What is the Vmax of this enzyme when enzyme concentration is equal to 0.2mg/mL? I understand the equation to find kcat is: kcat = Vmax/[E]t however,
we need to form a cyclohexanone with a methyl group at the 6 position and a 2,3-butanediol group (with both OH groups at the back (dashed lines)) at the 2 position. All carbons on the target need to come from the starting materials, but other than..
