Wanting to form nickel(II) cyanide, Ni(CN)2, a chemist adds hydrocyanic acid, HCN, to a solution containing Ni2+ ions hoping to precipitate Ni(CN)2. The important equlibria for this process are given below:
HCN(aq) <--> H+(aq) + CN-(aq) Ka=4.0x10^(-10)
Ni(CN)2(s) <--> Ni2+(aq) +2CN-(aq) Ksp= 3.0x1-^(-23)

a) what is the equilibrium constant, Knet, for the following reaction which describes the precipitation reaction the chemist wants to perform?
Ni2+(aq) + 2HCN(aq) <--> 2H+(aq) + Ni(CN)2(s)
Knet = ?

b) Can the chemist readily form Nickel (II) Cyanide in this manner?
c) The chemist runs the reaction and allows the solution to come to equilibrium before diluting the solution by a factor of 10. Calculate Q upon dilu
d) Will he get more or less Ni(CN)2 by diluting the solution in this fashion?

countershaft in Prob. 3–72, p. 152, is part of a speed reducing compound gear train using
20° spur gears. A gear on the input shaft drives gear A. Gear B drives a gear on the output
shaft. The input shaft runs at 2400 rev/min. Each gear reduces the speed (and thus increases
the torque) by a 2 to 1 ratio. All gears are to be of the same material. Since gear B is the
smallest gear, transmitting the largest load, it will likely be critical, so a preliminary analysis
is to be performed on it. Use a diametral pitch of 2 teeth/in, a face-width of 4 times the circu-
lar pitch, a Grade 2 steel through-hardened to a Brinell hardness of 300, and a desired life of
15 kh with a 95 percent reliability.

1) if b is meshing with another gear with a diameter d=16 in what would be the required teeth on Fb?

2)Determine factors of safety for pitting

Output with Vars.java

A variable like userNum can store a value like an integer. Extend the given program as indicated.

1. Output the user's input. (2 pts)
2. Output the input squared and cubed. Hint: Compute squared as userNum * userNum. (2 pts)
3. Get a second user input into userNum2, and output the sum and product. (1 pt)

Note: This zyLab outputs a newline after each user-input prompt. For convenience in the examples below, the user's input value is shown on the next line, but such values don't actually appear as output when the program runs.

Enter integer:
4
You entered: 4
4 squared is 16 
And 4 cubed is 64!!
Enter another integer:

The Burlington plant of Consumer Cosmetics is responsible for manufacturing all the lip gloss products that the company manufactures. In 2015 the plant had the following budgeted and actual costs.

Required

(a)      Head Office is complaining about cost over-runs. It says that all the manufacturing costs are higher than the budget in both $ and %. As manager of the plant, how would you respond to justify your position?

(b)     Ignoring price changes, etc., if you were told that the quantity to be manufactured in 2016 would be 1,000 kg, prepare the budget for 2016.

Risks and Controls

A. Tom works at a Fitness studio as a receptionist. His role is to verify that everyone who comes in is a member or pays a fee to come into the gym. He really needs to go to the toilet so he leaves the reception unattended and runs to the toilet.

B. Jill is the CFO of a company. She normally takes public transport and every day she works at home using her office laptop. On her way home she forgot her laptop in the bus.

C. Mike is a courteous employee of a financial company. The financial company has card readers at every door to make sure that only authorized personnel is able to access the building. Mike holds the door open for other people who are trying to get into the building.

Write down 5 examples of risks?

• What type of control is this (preventive, detective or corrective)?

The client was a young IT professional who wanted to start-up a new company. The idea was to combine virtual reality developments with online education which was getting quite popular after coronavirus pandemic in 2020. Furthermore, the client was getting ready to launch virtual offices as well. Test runs have shown a strong interest from many companies as this would allow to save a lot of money on office spaces, utilities and supplies.

you have also asked the client which criteria is the most important for the new company: (a) organizational requirements and costs, (b) liability of the owners, (c) the continuity of the business, (d) the transferability of ownership, (e) management control and regulations, (f) the ability to raise capital or (g) income taxes.

Question . Specify the most suited legal form of business for each above mentioned criterion and explain the reason. Answer: a, b, c, d, e, f, and g

M.F., age 62, is brought to the emergency department by her son. While visiting her, he became alarmed when he noticed his mother seemed to have problems speaking and forming words. The right side of her face also appears to be "drooping."

M.F. suffers from a history of atrial fibrillation, high blood pressure, and diabetes. She is taking anti-hypertensive medications. She used to smoke but she quit 4 years ago. Cardiovascular disease runs in her family. Her father died of a heart attack at the age of 52.

A CT scan rules out a brain hemorrhage.

What type of stroke is M.F. experiencing?

What area of M.F.'s brain appears to be affected?

What are some of M.F.'s risk factors for cerebrovascular disease?

What role may atrial fibrillation play in M.F.'s case?

Why is the CT scan information important?

What treatments are available for M.F.?

Oberweis is a dairy company based out of Chicago. Oberweis produces milk at a fixed rate of 6,000 gallons/hour. Oberweis serves clients who, in total, request 100,000 gallons of milk per day. Clients send trucks to pick up their orders, and trucks arrive uniformly from 8am to 6pm. If Oberweis runs out of milk, trucks will wait until enough is produced to satisfy their client’s requests. Per Oberweis policy, the company begins and ends each day with 24,000 gallons in finished goods inventory. The plant begins its daily production at 8am and closes once it has satisfied all client demand and replenished its finished goods inventory. In your analysis, treat trucks/milk as a continuous flow process.

1) If Oberweis were charged $30 per hour per waiting truck, how much would Oberweis be charged per day (in dollars)?

A coffee roaster in Richardson has opened a retail store adjacent to the production plant. The plant manager wishes to optimize the inventory costs of the company’s best-selling coffee. The annual demand for the coffee is 36,000 bags and the plant works 240 days per yr. The plant can roast the coffee at a rate of 300 bags per day. The cost to prepare the equipment to start a production run is $350 and the annual inventory carrying cost is $3.6 per year. Use 2 decimal places in your calculations (if needed) and round your final answer to the closest whole number.

1. What should be the optimum quantity of coffee to produce?

2. What is the maximum inventory achieved during a production run?

3. How many production runs are needed to meet the annual demand?

4. What is the average inventory of coffee?

5. What is the minimum total annual cost of producing and storing the company’s best-selling coffee?

You are considering constructing a new plant in a remote wilderness area to process the ore from a planned mining operation. You anticipate that the plant will take a year to build and cost $100 million upfront. Once built, it will generate cash flows of $15 million at the end of every year over the life of the plant. The plant will be useless 20 years after its completion once the mine runs out of ore. At that point you expect to pay $200 million to shut the plant down and restore the area to its pristine state. Using a cost of capital of 12%,
