There is a class of polyesters that have the general structure shown below. For example, in polyethylene terephthalate (PET) m =1. How would you expect the Tg ad Tm of these polymers to vary with m, given that the molecular weight of the chain is held constant? Give reasons for your answer. Also, assuming that you are now just considering one member of this class of polymers, say PET, how does the Tg vary with molecular weight, n.

Glycolic acid is used in the textile industry as a dyeing and tanning agent. Given that its acid dissociation constant (Ka) is 1.47 × 10-4 and its partition coefficient (KD) between water and benzene is 3.22, calculate the extraction efficiency of a single extraction when 50.00 mL of a 0.025 M aqueous solution of glycolic acid buffered to a pH of 3.00, is extracted once with 50.00 mL of benzene.
In order to improve the peptide separation by using a HPLC system, trifluoroacetic acid acts as mobile-phase modifier was added during the preparation of mobile phase. The preparation was performed by a postgraduate student as following:“2.851 g trifluoroacetic acid (MW: 114.02 g/mol) was made up to 500 cm3 in a graduated flask. To this solution, 50 cm3 of ethanol was added, and after mixing the mobile phase was placed in the solvent reservoir and pumping was commenced at 1.5 cm3 min-1.”Based on the given preparation procedure, identify THREE mistakes that were made.
10 Find the transition time of 20g naphthalene with the surrounding temperature as 30oC.Let the boiling tube has mass 25 g, diameter 2.5 cm and thickness 0.15cm. How much time does 30g of ice takes to melt at a surrounding temperature of -50C. (We are using a boiling tube having mass= 20g, radius=1.5cm, thickness=0.2cm.) In the above experiment, let the surrounding temperature is changed to 0oC. What will be the change in the transition time for ice?
