Imagine you have graduated and have just gotten a job in a fictionalized version of Paducah, KY, home of the world famous Dippin' Dots (Links to an external site.)Links to an external site.. You got the job by pitching a truly marvelous idea: The Grand Cone-yan, an ice cream festival as grand as any Court Days (Links to an external site.)Links to an external site. or Apple Festival (Links to an external site.)Links to an external site..

The centerpiece of the festival is a 10 foot tall ice cream cone filled with local ice cream dots.

The day before the festival the contractors have brought the truck of ice cream, and begin to fill the cone. After only a single minute, there is a foot of ice cream in your frozen glass cone. Since the entire cone is only 10 feet tall, you decide to come back in 10 minutes to witness the final filling.

You are shocked when you return to find the cone has only been filled to the 2 foot mark! (The worker politely corrects you to say it is actually 2 feet and 2 inches.) You give it another 10 minutes, but the cone is only 2 foot 9 inches filled.

Not knowing what else to do, you make a spreadsheet of the progress.

Time (minutes)	0	1	10	20	30	60	120
Height (feet, inches)	0' 0"	1' 0"	2' 2"	2' 9"	3' 1"	3' 11"	4' 11"

You wonder why they have slowed down so much, so you keep checking in every hour.

Time (hours)	1	2	3	4	5	6
Height (feet, inches)	3' 11"	4' 11"	5' 8"	6' 3"	6' 6"	6' 11"

After six hours you are worried the entire festival might fail, but you won't give up! You keep spreadsheeting.

Time (hours)	7	8	9	10	11	12
Height (feet, inches)	7' 4"	7' 8"	7' 11"	8' 3"	8' 6"	8' 9"

After 12 hours, you take a quick trip home to change clothes, and return to your spreadsheeting.

Time (hours)	13	14	15	16	17	18
Height (feet, inches)	8' 11"	9' 2"	9' 5"	9' 7"	9' 9"	10' 0"

Finally, late in the night, around 3am, it is complete. Your masterpiece. The Grand Cone-yan. But why did it take so long? It took a lot longer than 10 minutes. Why did the workers slow down so much? The first minute finished the first foot, but three feet took 30 minutes instead of 3 minutes. And now it's 3am!

The workers say that they filled at a steady rate of 13 gallons per hour, and that any faster would run the risk of drain freeze.

Your responses

1. What is wrong with the following argument?

If you really did 13 gallons per hour, then the 10 foot cone should have only taken 10 / 13 = 0.7 hours, less than an hour tops.

2. What is wrong the following question?

How do you convert gallons into feet?

3. Find an authoritative source for the volume of a cone. Give the formula and explain what each part of the formula means in this problem.

4. Most formulas will have both radius and height. Find a reasonable source for the relationship between the radius and height of an ice cream cone. Give an expression like

R = H

5. Calculate the volume of the cone using your formula. At a constant rate of 13 gallons per hour, how long should it have taken to fill up?

You may use the approximate formula V=0.02908882 h3 if the formula you discovered does not match at all.

6. There should still be a discrepancy between the V=0.02908882 h3 and the spreadsheet. Can you explain what likely happened?

This is my lab procedure... please answer the following

1. Describe how the extraction is used to isolate the camphor.

2. Describe the reaction occurring and explain the catalytic cycle involving NaClO.

2. Add 1.0 g (6.5 mmol) of borneol, then 4 mL of ethyl acetate and a magnetic stir bar to the round bottom flask. 3. Stir the mixture until the solid dissolves using the stir bar. While stiring, add 0.08 g sodium chloride and 1.5 mL of distilled water to the flask 4. Add 20 ml of bleach to the separatory funnel. Make sure the stop cock is closed to start with 5. Next add the bleach solution to the reaction mixture in small portions with while stirring for a period of 10 minutes or more Monitor the temperature to control the rate of addition so that the temperature remains below 50Â°C. Have an ice water bath nearby to cool the reaction mixture if it begins to approach 50Â°C. When the addition is complete, seal the flask with Paraflim and stir for 30 minutes or more 6. Continue to stir the mixture for 50 minutes at room temperature, then add another 0.03 g sodium chloride 7. Stir for a further 10 minutes, then add 15 mL distilled water 8. Add a "spatula tip of sodium bisulfite to reduce any unreacted NaCIO, then test the aqueous layer with starch-iodide paper: a blue-black color indicates that more sodium bisulfite is needed 9. Separate the layers using a separatory funnel. Drain the lower (aqueous) layer into a 50 mL Erlenmeyer and label it as flask A this is to be extracted further. Pour out the upper layer (ethyl acetate) into another 50 mL Erlenmeyer and label as flask B; this 10. Return the aqueous layer (from flask A) to the separatory funnel and extract three more times with 5 mL of ethyl acetate. Each 11. Now return the organic layer (in flask B) to the separatory funnel and extract this organic solution with 5 mL saturated sodium 12. Dry the organic layer in flask B further by adding some crystals of using sodium sulfate. Transfer the dried solution (by will be used to hold the organic extracts time put the upper organic layer into flask B, until you end up with one big organic extract chloride solution, placing the lower layer into flask A and the upper organic layer into flask B decanting) into a pre-weighed (labeled) 50 mL beaker and let it dry in the fume hood for 30 minutes. You should be left with a final white powder product of camphor. Weigh the flask to determine the amount of crude wet product. 13. Allow your product to dry (preferable in a desiccator) overnight and reweigh it the next day. Use the weight of the dried/purified product to determine the % yield 14. Assess the purity of the final product using FTIR spectroscopy

This is the only info I get

Organic Chemistry Laboratory II EXPERIMENTAL PROCEDURE . Borrow a stir bar from the instructor 2. Place 3.3 g of acetanilide into a 125-mL Erlenmeyer flask and then add 5 is of p-Nitroacetanilide mL of glacial (concentrated) acetic acid (CAUTION: strong irritant). Warm the flask on a hot plate in the hood until the acetanilide dissolves. Cool the flask in an ice bath to about 20Â°C; then add 5 mL of cold, concentrated sulfuric acid. The temperature of the mixture will rise to about 60Â°C. Chill the solution to about 10Â°C in an ice bath. (The solution may become very viscous.) 3. Mix 1.8 mL of concentrated nitric acid and 2.5 mL of concentrated sulfuric acid in a 50-mL Erlenmeyer flask (CAUTION: Use extreme care when preparing this nitrating mixture), and chill the flask in an ice bath for~4 minutes 4. When both solutions are cold, slowly add the nitrating mixture, 1 mL at a time, to the constantly stirred acetanilide solution. Keep the reaction flask in an ice bath so that the temperature of the reaction mixture is maintained between 10 - 20Â°C. The entire addition requires about 15 minutes. 5. After the addition is completed, allow the reaction to proceed at room temperature for 30 minutes (keep the stirrer going). Monitor the temperature; if it rises above 30Â°C, chill the flask in an ice bath to just below 30Â°C. Should the re-chilling be necessary, allow the reaction to proceed for an additional 10 minutes. 6. Pour the reaction mixture into a 250-mL beaker containing 50 mL of water and about 15 g of cracked ice. Stir the mixture for a minute or so during this time a light yellow solid should form. [If a white solid forms, then you have recovered unreacted acetanilide. If a dark yellow or yellow-orange solid is recovered, then the product has undergone hydrolysis. Should any of these two things occur, you must start the reaction all over again - consult with your instructor if you are unsure about the color.] 7. Vacuum filter the solution. Press down on the light yellow solid with a clean 50 mL beaker or Erlenmeyer flask to remove as much of the aqueous solution as possible. (CAUTION: Nitro compounds are toxic and can be absorbed through the skin.)
