Homework Answers
You can use water for the redissolution of peptides, there is no issue.
But the drying problem will arise, other than that it is quite ok!
[-NH-CH(R)-CO-NH-]n --H2O--> Dissolution takes place

After mixing for three hours, the product is extracted into Dichloromethane and the solvent is removed to give 5.5 g of a yellow oil. Question #31: Using the mmoles of nitrobenzene calculated earlier (45.5) and the molecular weight of the product (157.5 g/mol) predict the theoretical 100% yield of the product in grams. Round to the hundredths place. Question #32: Using this number predict the experimental yield (reminder, the reaction produced 5.5 g of product.) Round to the nearest whole...

When bonding teeth, orthodontists must maintain a dry field. A new bonding adhesive has been developed to eliminate the necessity of a dry field. However, there is concern that the new bonding adhesive is not as strong as the current standard, a composite adhesive. Tests on a sample of 10 extracted teeth bonded with the new adhesive resulted in a mean breaking strength (after 24 hours) of x = 5.42 Mpa and a standard deviation of s = 0.45 Mpa....

Let's say you have a mixture for which you want to check the composition. Unfortunately, after quite a while, and several TLC analyses using our system, no spots have moved up the plate. What change could you make in the TLC system to try to get at least one compound in the original mixture to move up the plate? 1- try a more polar solvent 2- try a less polar solvent 3- try a more polar adsorbent
