The triprotic acid has Ka1 = 1.0 x 10-3, Ka2 = 1.0 x 10-6, and an unknown value for Ka3. 1) Calculate the pH after 100.0 mL of KOH has been added. Calculate the pH after 150.0 mL of KOH has been added.The pH of the solution after 200.0 mL of KOH has been added is 8.00. Determine the value of Ka3 for this triprotic acid.

In the sun, 1000g of hydrogen fuses to 993g of helium while the other 7g of matter is converted into energy using Einstein's famous equation E=mc2, where c is the speed of light (3.0*108m/s).

~ What is the ratio of the energy released by the fusion of 1.0 kg of hydrogen to that released by fission of 1.0 kg of Uranium-235?

~Given the obvious advantage in energy production, briefly describe some of the difficulties in designing and operating a fusion power plant to explain why there are no commercial fusion power plants in operation today.

Profitability index

Estimating the cash flow generated by $1 invested in a project

The profitability index (PI) is a capital budgeting tool that is defined as the present value of a project’s cash inflows divided by the absolute value of its initial cash outflow. Consider this case:

Happy Dog Soap Company is considering investing $2,225,000 in a project that is expected to generate the following net cash flows:

Happy Dog Soap Company uses a WACC of 10% when evaluating proposed capital budgeting projects. Based on these cash flows, determine this project’s PI (rounded to four decimal places):

0.5588

0.7058

0.5882

0.6764

Happy Dog Soap Company’s decision to accept or reject this project is independent of its decisions on other projects. Based on the project’s PI, the firm should ........... the project. (Reject or accept)

By comparison, the NPV of this project is ........... (-$916,329, -$733,063, -$1,007,962) . On the basis of this evaluation criterion, Happy Dog Soap Company should ........ (invest or not invest) in the project because the project ...... (will not or will) increase the firm’s value.

A project with a negative NPV will have a PI that is ........ (greater then 1.0, equal to 1.0 or less than 1.0) ; when it has a PI of 1.0, it will have an NPV ............. (Greater then $0, equal to $0 or less than $0)

a) There should be a difference in your results between the solubilities of biphenyl and benzophenone in methyl alcohol. (Biphenyl and methyl alcohol are partially soluble..... and benzophenone and methyl alcohol are soluble). Using chemical structures, clearly illustrate the intermolecular force responsible for this difference in solubility for the 2 compounds.

b) explain the solublity behavior of the indicated alcohol in water and hexanes. In each case, be sure to indicate the relevant intermolecular forces between solute/solute, solvent/solvent, and solute/solvent. Case 1: methyl alcohol. Case 2: 1-butanol. Case 3: 1-octanol. (Information needed: methyl alcohol is soluble in water and partially soluble in hexane. 1-butanol and 1-octanol both are insoluble in water and both soluble in hexane.

c) give a brief explanation that explains the solublity trend observed for benzoic acid. you must explicity descrive the intermolecular forces involved. (information: benzoic acid is insoluble in water. soluble in 1.0 NaOH but when you add 6.0 M HCl to the same tube, it becomes insoluble. benzoic acid is insoluble in 1.0 M HCl)

d) give a brief explanation that explains the solublity trend observed for benzoic ethyl-4-aminobenzoate. you must explicity descrive the intermolecular forces involved. (information: is ethyl-4-aminobenzoate insoluble in water. isoluble in 1.0 NaOH. soluble in 1.0 M HCl but when you add 6.0 M NaOH to the same tube, it becomes insoluble)

1. Consider a polymer with a number average molecular weight of 6,200 daltons. This polymer is made of two different fractions. The first fraction has 40 molecules whereas the second one has 60 molecules with molecular weight of 7,000 daltons. Calculate:

(a) The molecular weight of the first fraction of this polymer (1.0 point).

(b) The weight average molecular weight (1.0 point).

2. Consider a 18 g polymer sample made of 3 different fractions with the characteristics listed in the following table.

(a) Calculate the number average molecular weight of this polymer (2.0 points).

(b) If the dispersity of this polymer is 2.5, calculate its weight average molecular weight (1.0 point).

3. Consider a polymer with the characteristics described in the following table.

(a) Calculate the number average molecular weight of this polymer (2.0 points).

(b) Calculate the weight average molecular weight of this polymer (2.0 points).

(c) Calculate the polydispersity index (0.5 point).

(d) Is the molecular weight distribution narrow or wide? (0.5 point)
