Draw the repeat unit of the copolymer used for artificial skin growth, which is formed by condensation polymerization of lactic
acid and glycolic acid
2 answers:
Answer:
On the attached document.
Explanation:
Hello,
Condensation polymerization reactions come from the reaction of two gathering organic chains to produce a polymer and water. In this manner, when lactic acid reacts with glycolic acid a break in the O-H bond of their carboxyl group is carried out in order to yield the monomeric unit which combines both lactate and glycolate. In addition to the aforesaid fact, the beginning of such polymer is given by the glycolate and the end by the lactate and water must be yielded as well. You can substantiate the previous description by checking out the the attached picture in which "n" refers to the repetition of the formed copolymer which is the product indeed.
Best regards.

Answer:
To determine the enthalpy and entropy of dissolving a compound, you need to measure the Ksp at multiple temperatures. Then, plot ln(Ksp) vs. 1/T. The slope of the plotted line relates to the enthalpy (ΔH) of dissolving and the intercept of the plotted line relates to the entropy (ΔS) of dissolving.
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us use the thermodynamic definition of the Gibbs free energy and its relationship with Ksp as follows:
Thus, by combining them, we obtain:
Which is related to the general line equation:
Whereas:
It means that we answer to the blanks as follows:
