EXPERIMENT #4 – PREPARATION OF o-CHLOROBENZOIC ACID

1. PREPARE A SOLUTION OF CuCl AS FOLLOWS: Dissolve CuSO4∙5H2O (2.34 g) and pure NaCl (0.62 g) in water (8 mL) in a 50 mL Erlenmeyer flask. Warm on a hot plate to dissolve. Add a solution of sodium bisulphite (0.56 g) in water (6 mL) to the hot solution, with constant shaking over a period of about 5 minutes. Cool to room temperature in an ice bath, and decant the supernatant liquid from the colourless CuCl. Wash the precipitate twice by decantation with water containing a little (approximately 1% (v/v) solution) sulphurous acid (HSO3 ‐ + H+ →H2SO3), to prevent oxidation. Dissolve the CuCl in concentrated HCl (4 mL). Stopper the flask and cool in an ice‐salt mixture (0‐5oC) while the diazonium salt is being prepared.

2. PREPARE A DIAZONIUM SALT AS FOLLOWS: In a 125 mL conical flask, dissolve o‐ aminobenzoic acid (anthranilic acid, 0.94 g) in a solution containing conc. HCl (1.4 mL) and water (8.2 mL). Cool the solution to 0 oC. Slowly add a cold solution of NaNO2 (0.46 g) in water (1.6 mL). Do not allow the temperature to rise above 10 oC during this procedure. Add a small amount of urea (a few crystals) to the mixture and cool the resulting solution in an ice bath.

3. PREPARE o-CHLOROBENZOIC ACID AS FOLLOWS: Transfer the cold CuCl solution to a 150 mL beaker. Slowly add, with stirring (use long glass rod), the cold diazonium salt solution to the cold CuCl solution. Watch for foaming. Allow the mixture to stand for 20 minutes at room temperature with frequent stirring. Vacuum filter the precipitated o-chlorobenzoic acid and wash the product with a small amount of cold water.

4. RECRYSTALLIZE AS FOLLOWS: Clean the Buchner funnel and place it along with a 500 mL vacuum flask into the oven at 105 oC. In a 150 mL beaker, add the crude product, a small amount of charcoal, water (~20 mL) and ethanol (~2.6 mL). Heat to a gentle boil, stirring the mixture periodically. When the product has dissolved, quickly filter through the hot Buchner funnel (PRERINSE FILTER PAPER WITH BOILING WATER) in order to remove the charcoal before the o‐chlorobenzoic acid is allowed to 26 crystallize. Allow to cool to room temperature. Vacuum filter the recrystallized product. Dissolve a few crystals of the product in ethanol and spot it on a TLC plate and label it “R”. Likewise dissolve a few crystals of anthranilic acid in ethanol and spot that on a TLC plate as well, labelling it as “SM”. Develop the TLC plate as usual, taking note of the solvent used. Determine the m.p. and percent yield of the dried product next week while doing experiment #5.

If the experiment were to be performed exactly this way, how would one determine the limiting reagent of the reaction for the percent yield calculation? What should be the limiting reagent of this reaction? When I ran this experiment, I was able to form 0.43 g of product.

Thanks for your help!

A heat exchanger with 1 body - 4 pipe passages and 109 pipes (2.6 cm diameter each, 4 m long thin wall per passage) at each passage will be used to heat the air. The water enters the pipes with a mass flow of 8 kg / h at 350 K temperature and the air enters the body with a mass flow of 18 kg / h at a temperature of 15 C. The pollution factor of the sediment formed inside the pipe over time is 0.0026 m2K / W. The transport coefficients on the inner and outer surfaces of the pipes are estimated at 450 and 200 W / m2K, respectively. Using specific temperatures at 25 C for air and water

a-) The effectiveness of the heat exchanger by drawing the shape of the problem,

b-) Heat transfer rate (kW),

c-) Calculate the outlet temperatures (C) of the water and air and show the temperatures in the T_L diagram.

a. Two years after the bonds were issued, the going rate of interest on bonds such as these fell to 8%. At what price would the bonds sell? Round the answer to the nearest cent. $

b Suppose that 2 years after the initial offering, the going interest rate had risen to 15%. At what price would the bonds sell? Round the answer to the nearest cent. $

Python 3.7:

1. Write a generator expression that repeats each character in a given string 4 times. i.e. given “gone”, every time you call the next method on the generator expression it will display “gggg”, then “oooo”, … etc and instantiate it to an object called G.  G = (…..) # generatorExpression object

2. Test and verify that iter(G) and G are the same things. What does this tell you about the nature of a Generator object/expression?

3. Assign Iter(G) to an iterator object called it1 and advance it to the next element by using next method.

4. Instantiate a new Iter(G) object called it2. Use the next method and advance it to the next element. Observe the result and compare it with the results of it1.

5. Does the new Iter(G) object start the iterator from the start of the string object? Write down your understanding/conclusion from this experiment.

6. How can you get back the Iter(G) to point back to the beginning of the string?

A person deposits​ $1,000 in an account every year for four years​ (Years 1 through​ 4), and withdraws half of the balance of the account at the end of Year 4. They put nothing in the account for two years​ (Years 5 and​ 6), then deposit​ $1,500 in the account every year for four more years​ (Years 7 through​ 10).

4. Flying High is currently an all-equity firm. It has 1 million shares outstanding and the current share price is $10 per share. The management plans to issue $3 million of perpetual debt and use the proceeds to buy back part of its shares. The debt cost of capital at the new capital structure is 7%. The corporate tax rate is 20%.

Assume the EBIT each year will be high enough so the 30 percent limit on the interest deduction will not be reached. (Therefore the entire interest expense is tax deductible.)

a. Calculate the annual interest tax shield associated with this debt issue.

b. Calculate the present value of the interest tax shields, assuming the interest tax shields have the same risk as the firm's debt.

c. Calculate the value of the firm after the change in capital structure.

d. Calculate the market capitalization after the change in capital structure.

Quantitative Problem 1: Beasley Industries' sales are expected to increase from $4 million in 2019 to $5 million in 2020, or by 25%. Its assets totaled $2 million at the end of 2019. Beasley is at full capacity, so its assets must grow in proportion to projected sales. At the end of 2019, current liabilities are $780,000, consisting of $160,000 of accounts payable, $450,000 of notes payable, and $170,000 of accrued liabilities. Its profit margin is forecasted to be 4%, and its dividend payout ratio is 70%. Using the AFN equation, forecast the additional funds Beasley will need for the coming year. Do not round intermediate calculations. Round your answer to the nearest dollar.
$  

The AFN equation assumes that ratios remain constant. However, firms are not always operating at full capacity so adjustments need to be made to the existing asset forecast. Excess capacity adjustments are changes made to the existing asset forecast because the firm is not operating at full capacity. For example, a firm may not be at full capacity with respect to its fixed assets. First, the firm's management must find out the firm's full capacity sales as follows:

Next, management would calculate the firm's target fixed assets ratio as follows:

Finally, management would use the target fixed assets ratio with the projected sales to calculate the firm's required level of fixed assets as follows:

Required level of fixed assets = (Target fixed assets/Sales) × Projected sales

Quantitative Problem 2: Mitchell Manufacturing Company has $1,700,000,000 in sales and $350,000,000 in fixed assets. Currently, the company's fixed assets are operating at 70% of capacity.

1. What level of sales could Mitchell have obtained if it had been operating at full capacity? Do not round intermediate calculations. Round your answer to the nearest dollar.
   $  
2. What is Mitchell's Target fixed assets/Sales ratio? Do not round intermediate calculations. Round your answer to two decimal places.
   %
3. If Mitchell's sales increase by 60%, how large of an increase in fixed assets will the company need to meet its Target fixed assets/Sales ratio? Do not round intermediate calculations. Round your answer to the nearest dollar.
