1. Is the Haber process an exothermic or endothermic reaction?
2. Write a balanced thermochemical equation with phase labels for the Haber process with the heat energy as part of the equation.
3. What is the theoretical yield of ammonia(in grams) if 17.15 grams of nitrogen gas and 10.95 grams of hydrogen gas are allowed to react?
4. Based on your theoretical yield, what is the percent yield of ammonia if only 11.5 grams of ammonia is produced?
5. How much heat energy (in Kj) will be absorbed or released if 11.5 grams of ammonia is produced? State whether the energy will be absorbed or released.
6. Compare and contract the positive and negative effects that result from the use of the Haber process. Discuss the controversy that followed the awarding of the Noble Price in Chemistry to Haber. Based on this discussion, do you think Haber should have been awarded this prestigious award for his work? Explain

Money reports that the average annual cost of the first year of owning and caring for a large dog in 2017 is $1,448. The Irish Red and White Setter Association of America has requested a study to estimate the annual first-year cost for owners of this breed. A sample of 50 will be used. Based on past studies, the population standard deviation is assumed known with
σ = $265.

A. What is the margin of error for a 95% confidence interval of the mean cost in dollars of the first year of owning and caring for this breed? (Round your answer to nearest cent.)
B. The DATAfile Setters contains data collected from fifty owners of Irish Setters on the cost of the first year of owning and caring for their dogs. Use this data set to compute the sample mean. Using this sample, what is the 95% confidence interval for the mean cost in dollars of the first year of owning and caring for an Irish Red and White Setter? (Round your answers to nearest cent.)

The essay question concerns judicial interpretation of the Sherman Act, section 2 from the early days through the Grinnell case. How is the problem of “market definition” relevant in section 2 cases? Is monopolization illegal per se? Be prepared to explain the change in approach in the Alcoa case from the early days or “era of leniency” with respect to the types of evidence necessary to establish “evident purpose” or “intent to monopolize.” Also, according to the standards set in the Grinnell decision, when is the structural condition of monopoly “safe” from section 2 prosecution?

Produce a 4 page report containing employment growth, industry growth, job requirements, salary data, benefit data (regularly offered), and any other relevant data. Benefits include vacation, overtime, sick leave, personal leave, bonuses, shift differential, life insurance, short & long term disability, pension, 401k, etc. You can use bls.gov for some of the data and more specific sites for more possible data. So if you'd like to join the NYPD, going on the NYPD's website would be a wonderful place to get started. Also, write a section about the pros and cons of the jobs such as stress, late nights, work from home opportunities, transit subsidies, etc. The purpose of this assignment is to analyze compensation packages alongside your personal futures! Each occupation should provide about 2 double spaced pages and at least one graph containing whatever data you deem most relevant. Within these pages provide robust analysis of the numbers; however, also provide a good story

In the Musculoskeletal System subsection of the Surgery section in your CPT book, it discusses the following types of treatment: closed treatment, open treatment, and percutaneous skeletal fixation. What do each of these terms means? What are the differences between each of these types of treatment? Choose one of the types of treatment and give an example of a procedure that would be performed using that method, along with the code that would be assigned for the example.
