DATA:

Calibration Solution 0.2M Fe(NO3)3 in 0.5M HNO3 0.002M KSCN in 0.5 HNO3 0.5M HNO3 Absorbance
#1 5mL .50 4.5 .339

#2 5 2 3 .212
#3 5 3 2 .308
#4 5 4 1 .406
#5 5 5 0 .672

1. Concentration of Fe(SCN)2+ in calibration solutions- recall that the concentration of Fe(SCN)2+ in the calibratic solutions is essentially the concentration of the SCN initially in the solution. So, determine the concentration of SCN- initially in each of the 10.0mL calibration solutions. This is a simple dilution!

Answer:

#1 - 0.0001

#2 - 0.0002

#3 - 0.0003

#4 - 0.0004

y = 3929x - 0.041

slope = 3929

r2 = 0.9992

2. What is the value of eb?

3. For each sample, account for the dilution effect and determine the intial concentration of the reactants in the 10mL samples:

Equilibrium Solution (Fe(NO3)3)0 / M [KSCN]0 /M

4. For each sample, calculate the equilibrium concentration of Fe(SCN)2+ using the value of eb that you found.

Equilibrium Solution Absorbance Fe(SCN)2+ eq

I need to know how to solve this on paper and on a ti-84

A new otc medicine to treat a sore throat is to be tested for its effectiveness. The maker of the drugmedicine take 2 random samples of 25 individuals showing symptoms of a sore throat. Group 1 receives the new medicine and group 2 recieves a placebo. After a few days of the medicine, each group is interviewed and asked how they would rate their comfort level on a scale of 1-10 ( 1 being the most uncomfortable). The results are below. Is there sufficient evidence to conclude the variance in scores from group 1 is less than the variance of scores in group 2? test at a alpha=0.01

Facts: Opportunity Landscaping Inc. (Opportunity) appreciated your assistance in preparing their 2018 Federal income tax return....

Facts: Opportunity Landscaping Inc. (Opportunity) appreciated your assistance in preparing their 2018 Federal income tax return. As a result, they have come to you for advice on acquiring new facilities for their manufacturing operations. They plan to take access to their new facilities on January 2, 2020.

The corporation has the opportunity to purchase an appropriate facility in suburban Chicago for $90,000,000 ($87,000,000 for the factory building; $3,000,000 for the land). If they purchase the facility, they would finance the acquisition via a 15-year mortgage at 3.5% interest with a $18,000,000 down payment (due at closing on January 2, 2020). The mortgage would be payable annually in arrears (i.e., the first mortgage payment would be due January 2, 2021). Real property taxes on the facility in 2020 would be $1,000,000 (the property taxes are also due annually in arrears with 2020 taxes due on January 2, 2021). Further, Opportunity estimates that property taxes will increase annually at a rate of 3% in years subsequent to 2020.

As an alternative, a local real estate investor has offered to purchase the facility and lease it to the corporation. The investor would require Opportunity to sign a 7-year non-cancelable lease. The first lease payment of $3,700,000 would be due on January 2, 2020. Lease payments will increase by 4% each year during the term of the lease with the final lease payment due on January 2, 2026. In addition, the lease would require a refundable deposit of $1,850,000 (payment due on January 2, 2020) against significant damages to the facility; this deposit will be refunded to the corporation on January 2, 2027 (when the occupancy ends and assuming that there are no significant damages).

Opportunity must decide whether to lease or buy the facility. In order to make a proper decision, the corporation will assume that it could sell the facility (building and land) on January 2, 2027 for $100,000,000. Under this scenario, they would make their final mortgage and property tax payments on January 2, 2027 and then sell the facility.

Opportunity’s Federal corporate tax rate is 21% and it uses a 7% discount rate to compute the present value of its future cash flows. For purposes of this analysis, assume that all cash flows occur at the beginning of the respective year.

Required:

1. Based on the above facts, which option (lease or buy) minimizes Opportunity’s after-tax cost of obtaining the facility?

2. The local real estate investor has provided an option for Opportunity to consider. Under this option, a payment of $12,000,000 is due on January 2, 2020. If this payment is made, no deposit is required and the payment is deemed to cover the first three years of the lease. On January 2, 2023, lease payments resume with a $4,000,000 lease payment due (and a 4% increase in the lease payment each year for the remainder of the lease term). Is this an alternative that Opportunity should consider? Read and apply the materials in text Section 6-2d as part of your analysis.

3. Opportunity’s CFO is not certain that the current 21% Federal tax rate will be maintained over the next seven years. She feels that an increase in the Federal rate to around 30% is likely at some point in the near term. As a result, she would like to know how your analysis would be affected if the Federal income tax rate increased to 30% on January 1, 2025.

I have calculated and found that the NPV for the lease option is ($19,516,098). I have also used the PMT function on excel and found that the annual mortgage payments are $6,251,405 (15 years; $72 million; 3.5% interest rate). I need help computing the NPV for the buy option in order to decide which option is best.

You are studying a plant that requires a period of cold treatment before it will flower. You subject a plant to cold treatment, return it to temperatures favorable for growth, and then compare the chromatin state of the DNA taken from:

(1) meristem cells from a shoot that originated before the cold treatment;

(2) meristem cells from a shoot that developed after the cold treatment;

(3) ovule egg cells from a flower on stem 1;

(4) seeds from a flower on stem 2.

You find that the chromatin states are the same within but differ between which two groups?

Write a program in C# for a Cricket match using Jagged Arrays. The name of the project will be on your name. It has the following modules:

  • Create two functions in class Cricket_Match for random numbers generation.
    • The first function generates 1-6 numbers which is known as balls played by each player.
    • The second function generates a 0-6 number which is known as the score produced against each ball by an individual player.
  • In the main show the individual player score.
  • Show the total score.

Note: Random numbers are generated using the following function:

Random rnd = new Random();

int num = rnd.Next(1, 6);//Between 1-6
