Part D

When solving problems involving stoichiometric coefficients, the first step is to make sure you have a balanced chemical equation. Then, you determine the limiting reagent by using the coefficients from the balanced equation. You can keep track of the amounts of all reactant and products before and after a reaction using an ICF table. Completing the ICF table will also allow you to determine the limiting reagent, and the amount of product formed assumes that the reaction runs to completion with 100% yield. Parts A and C explore these steps in more detail. Let us consider another reaction.

Ammonia and oxygen react to form nitrogen monoxide and water. Construct your own balanced equation to determine the amount of NO and H2O that would form when 3.40 mol  NH3 and 4.71 mol  O2 react.

Express the amounts in moles to two decimal places separated by a comma.

Part a

A farmer applies 1705 kg of a fertilizer that contains 10.0% nitrogen to his fields each year. Fifteen percent (15.0%) of the fertilizer washes into a river that runs through the farm.

If the river flows at an average rate of 0.315 cubic feet per second, what is the additional concentration of nitrogen (expressed in milligrams of nitrogen per liter) in the river water due to the farmer's fertilizer each year? Answer: ? mg/L

Part b

Heptane and water do not mix, and heptane has a lower density (0.684 g/mL) than water (1.00 g/mL). A 100-mL graduated cylinder with an inside diameter of 3.22 cm contains 36.8 g of heptane and 34.8 g of water. What is the combined height of the two liquid layers in the cylinder? The volume of a cylinder is π r²h, where r is the radius and h is the height. Answer: ? cm

An article in Solid State Technology, "Orthogonal design for process optimization and its application to plasma etching" by G.Z.Yin and D.W.
Jillie (May, 1987) describes an experiment to determine the effect of the
C2F6 flow rate on the uniformity of the etch on a silicon wafer used in
integrated circuit manufacturing. All of the runs were made in random order. Data for two flow rates are as follows:

C2F6     Uniformity Observation
Flow 1      2      3      4     5      6

125   2.7   4.6 2.6   3.0   3.2   3.8

200   4.6   3.4   2.9   3.5   4.1   5.1

a) Does C2F6 flow rate affect average etch uniformity? use a=0.05

b) What is the P-value for the test in part (a)

c)Does the C2F6 affect the wafer-to-wafer variability in each uniformity? use a0.05

d) Draw box plots to assist in the interpretation of the data from this experiment

Suppose there are two consumers, A and B.

The utility functions of each consumer are given by:

UA(X,Y) = X^1/2*Y^1/2

UB(X,Y) = 3X + 2Y

The initial endowments are:

A: X = 4; Y = 4

B: X = 4; Y = 12

a) (10 points) Using an Edgeworth Box, graph the initial allocation (label it “W”) and draw the

indifference curve for each consumer that runs through the initial allocation. Be sure to label your graph

carefully and accurately.

b) (3 points) What is the marginal rate of substitution for consumer A at the initial allocation?

c) (3 points) What is the marginal rate of substitution for consumer B at the initial allocation?

d) (2 points) Is the initial allocation Pareto Efficient?

ou are trying to pick the least-expensive car for your new delivery service. You have two choices: the Scion xA, which will cost $20,500 to purchase and which will have OCF of –$2,500 annually throughout the vehicle’s expected life of three years as a delivery vehicle; and the Toyota Prius, which will cost $29,000 to purchase and which will have OCF of –$1,300 annually throughout that vehicle’s expected 4-year life. Both cars will be worthless at the end of their life. You intend to replace whichever type of car you choose with the same thing when its life runs out, again and again out into the foreseeable future.     

The accompanying data are the number of wins and the earned run averages​ (mean number of earned runs allowed per nine innings​ pitched) for eight baseball pitchers in a recent season. Find the equation of the regression line. Then construct a scatter plot of the data and draw the regression line. Then use the regression equation to predict the value of y for each of the given​ x-values, if meaningful. If the​ x-value is not meaningful to predict the value of​ y, explain why not.

​(a) x=5 wins ​(b) x=10 wins ​(c) x=21 wins ​(d) x=15 wins. The equation of the regression line is y with equals ____xplus ______. ​(Round to two decimal places as​ needed.)

Programming Human Concentration Human contains a brain that has several thought areas. Awareness is defined by understanding (focusing) of a thought area, and Concentration is defined focusing your awareness into a thought area for a longer duration of time. Using Object-Oriented Design, program this concept to demonstrate concentration.

Design Using Object Oriented Principles ---------------------------------------

Let's first think through all the Classes to be created: 1. Human 2. Brain 3. ThoughtArea You can consider defining properties in each of these classes. Following methods should be written for this project.

You have to decide which classes to put the methods in

1. awareness() 2. focus() 3. concentration()

Design two test cases to show concentration.

Grading Criteria 1. Object Oriented Programming principles are used. 2. Coding conventions are followed. 3. Test runs are provided. 4. Class diagrams are provided.

The company sold 12,500 units in the South region and 5,000 units in the North region. It determined that $125,000 of its fixed selling and administrative expenses is traceable to the North region, $75,000 is traceable to the South region, and the remaining $48,000 is a common fixed cost. The company will continue to incur the total amount of its fixed manufacturing overhead costs as long as it continues to produce any amount of its only product.
