Titration Curve of unknown Acid

Molarity of NaOH =.172

1. Your unknown acid is one of the following: oxalic acid (H2C2O4*2H20, pKa1=1.27, pKa2=4.27), citraconic acid (C5H6O4, pKa1=2.29, pKa2=6.15), or Maleic Acid (C4H4O4, pKa1=1.92, pKa2=6.09). These acids are classified as diprotic. Calculate the molar mass for your acid using the average mass from trials 1 and 2 and the average volume at the first equivalence point; then redo the calculation using the average mass from trials 1 and 2 and the average volume at the second equivalence point.

2. Using the average molar mass at the second equivalence point that you calculated in question 1, and your average values of pKa1 and pKa2, indentifiy your unknown acid. Explain.

Emma has provided to you a listing of the transactions she has undertaken throughout the financial year to assist you in completing her 2015 income tax return. Sale of a block of land for $1,000,000: Emma purchased the land as an investment in 1991. The purchase price was $250,000, plus $5,000 in stamp duty, $10,000 in legal fees. To fund the purchase, she took out a loan on which she paid interest totalling $32,000. During the period of ownership her council rates, water rates and insurance totalled $22,000. In January 2005 a dispute occurred with a neighbour over the use of the land and legal fees incurred amounted to $5,000 in resolving this dispute. Before putting the property on the market $27,500 was spent to remove a number of large dangerous pine trees that were on the land. Advertising, legal fees and agent’s fees on the sale of the land were $25,000. Sale of Emma’s 1000 shares in Rio Tinto for $50.85 per share: Emma paid brokerage fee of 2% on the sale. Emma initially purchased the shares for $3.5 per share in 1982. Sale of a stamp collection Emma had purchased, from a private collector, in January 2015 for $60,000: Emma sold the collection at auction for $50,000. Auction fees totalled $5,000 for the sale. Sale of a grand piano for $30,000: It was initially bought for $80,000 in 2000. HI6028 Taxation Theory, Practice and Law Individual Assignment T2.2019 5 Advise Emma of the capital gain tax (CGT) consequences of her transitions. Ignore indexation. Your answer must include references to relevant tax law and or cases.

Prepare a 2.00 L of a 2.00 M buffer of pH 4.35. You can use citric acid (pka 3.09, 192.1 g/mol) and NaOH (10.0 M). Calculate how much of each reagent (and water) to make the buffer (show work).

The answers are:

Citric acid: 786 g, NaOH: 514 mL, water: 1.486 L

How do you get to these results?

For 530.0 mL of a buffer solution that is 0.155 M in CH3CH2NH2 and 0.145 M in CH3CH2NH3Cl, calculate the initial pH and the final pH after adding 0.020 mol of HCl.

the previous one I saw it, I wonder how to do the last one.

Read carefully
See the photo of the algorithm below after reading these instructions: write a program in Python 3 which uses a list. Your program will use a list to store the names and exam scores of students. The program starts by asking how many results will be entered. Then a loop will be used to enter the name and score for each student. As each name and score is entered it is appended to a list (which was initially empty). When the loop is finished (i.e. all scores are entered) the program ends by printing the list.

Make a copy of your Lab6A.py file to Lab6B.py. Amend the comments accordingly for these instructions. Send the list you created in Lab 6A to a function which returns a list of names of all above average students.

A population of values has a normal distribution with μ=99.5 and σ=83.2. You intend to draw a random sample of size n=197. Please answer the following questions, and show your answers to 1 decimal place.

Find P77, which is the value (X) separating the bottom 77% values from the top 23% values. P77 (for population) =

Find P77, which is the sample mean (¯x) separating the bottom 77% sample means from the top 23% sample means. P77 (for sample means) =

Evaluate the effect of each shock below using first the classical model and second the Keynesian model. For the Classical model, include graphs of the goods market, the labor market, and the money market. For the Keynesian model, include an IS-LM-FE graph, an Aggregate Supply – Aggregate Demand graph, and a graph of labor market equilibrium with efficiency wages. For the Keynesian model, include short-run effects, while the price is constant, and long run effects after the price has fully adjusted.

1. There is a permanent increase in the money supply.
2. There is an increase in expected future productivity (the z in the production function).
3. There is an increase in government spending financed by an increase in expected future taxes.
4. There is an increase in the price of oil which reduces total factor productivity (z).

The combination of sodium chlorite and acetic acid forms hypochlorous acid (HOCl), which is the active ingredient in this reaction. Draw the arrow pushing mechanism of your reaction, using HOCl as reagent.

5. The price of trade

Suppose that Spain and Germany both produce fish and wine. Spain's opportunity cost of producing a bottle of wine is 3 pounds of fish while Germany's opportunity cost of producing a bottle of wine is 11 pounds of fish.

By comparing the opportunity cost of producing wine in the two countries, you can tell that   has a comparative advantage in the production of wine and   has a comparative advantage in the production of fish.

Suppose that Spain and Germany consider trading wine and fish with each other. Spain can gain from specialization and trade as long as it receives more than   of fish for each bottle of wine it exports to Germany. Similarly, Germany can gain from trade as long as it receives more than   of wine for each pound of fish it exports to Spain.

Based on your answer to the last question, which of the following prices of trade (that is, price of wine in terms of fish) would allow both Germany and Spain to gain from trade? Check all that apply.

2 pounds of fish per bottle of wine

1 pound of fish per bottle of wine

5 pounds of fish per bottle of wine

7 pounds of fish per bottle of wine
