This assignment is designed to give practice at determining the thermodynamic data for a reaction that is of some industrial importance. For the compound assigned, go to the library and find out how the compound is prepared industrially. Some compounds are prepared by a number of methods. Choose only one method to discuss. The narrative should not be long (half a page maximum). Include special apparatus, and write a balanced equation for the reaction. The processes assigned can usually be...

Sodium Borohydride Reduction Reaction 1. Dissolve 600 mg of your carbonyl compound in 3 mL of methanol. Cover the flask with aluminum foil when not adding reagents or taking TLC samples to keep any water from getting in. 2. Cool your flask to 0° C using ice/water. 3. Allow to stir in the ice for 2 minutes then slowly add 0.4g of NaBH4 to your solution, then remove from ice bath and stir at room temperature. 4. After 10 min,...

I have a question for my homework that says to react the following compounds with one equivalent of NBS with CCl4, and that they give only one major product. Then we have to explain why we gave our answers. I think this was just an accident that my professor left it out of the question, but wouldn't the reaction with NBS and CCl4 also need heat or light and peroxides to work? I've done the questions as if they were...

Remember that albinism is a recessive Mendelian trait. A rabbit breeder has one albino rabbit with the genotype "aa." He also has a brown and white-colored rabbit (pictured) with the genotype Aa (it had a single albino parent, and one brown-colored, brown-eyed parent). The breeder is wondering whether these two rabbits will produce any albino offspring, and wants to know on average how many offspring will be albino from a cross between his two rabbits? What would you tell him?...

Are there any ideas, biases, or assumptions implicit in the text? How does that affect the conclusions that you are able to draw? The auditor uses planning materiality (or overall materiality) in determining whether the financial statements overall are materially correct. In planning the audit, auditors consider planning materiality in terms of the smallest aggregate level of misstatements that could be material to any one of the financial statements. After determining planning materiality, the auditor uses performance materiality to determine...

Why does the scheduling function depend on the planning function? Which one must be done first? Why? Describe what an activity estimated duration is. How is it determined? Why might a contractor prefer to state a project completion time in terms of number of days after the project starts rather than a specific date? Give some examples of instances when this would be appropriate. Why is it important to determine the critical path of a project? What happens if activities...

4. Davisson Germer Problem: You are working in a lab developing useful new materials. One characteristic that is very important for materials, particularly for their sensitivity to corrosion, is the structure of the surface. So your boss gives you the challenge of finding out the surface structure of chunks of new material that are being created and analyzed in the lab. You may want to explore some of the simulations we've used in class which are available from the course...

MIPS ASSEMBLY Have the user input a string and then be able to make changes to the characters that are in the string until they are ready to stop. We will need to read in several pieces of data from the user, including a string and multiple characters. You can set a maximum size for the user string, however, the specific size of the string can change and you can’t ask them how long the string is (see the sample...
