Give examples from the literature of metal complexes with coordination numbers (CN) of 2, 3, 4, 5, 6, 7 and 8 (formula, structure). What is the highest Coordination Number found for a metal ion?

a) Suppose each of the following confidence intervals were calculated using the same sample. Circle the interval that is at the lower confidence level. State the sample proportion that was used to construct these intervals. (.25, .35), (.24, .36)

b) Suppose you want a confidence interval to be more narrow. What two things can you do to achieve this?

c) For a given sample, which would you prefer, a wider interval or a more narrow one? Why?

d) Suppose your sample proportion is 0.17, with n = 100. How many “successes” were in your sample?

e) Suppose you have a sample with n = 27. Nine of your sample values are found to have the characteristic of interest. Are the 4 conditions required to do a confidence interval met?

f) True or False: a 95% confidence interval for p always contains p.

Hi Can someone explain how the the output was achieved in details for this java question?

public class Example
  
{
public static void main(String [] args)
{
int a = 6, b = 5, i , num1, num2;
for (i = 1; i <= 3; ++i)
{
num1 = method1(a, b);
num2 = method2 (a, b);
System.out.println (num1 + " " + num2);
a = a + 2;
b = b - 1;
}
}
public static int method1 (int c, int d)
{
c = c + d;
return c;
}
public static int method2 (int e, int f)
{
f = f + e * 2 ;
return f ;
}
}

output

Linda invest 25000 for one year part is invested at 5% another part at 6% and the rest at 8%. the total income from all three investments is $1600. the income from the 5% and 6% investments is the same as the income from the 8% investment. find the amount invested at each rate.

Given the following data:

3FeO(s) + CO2(g) → Fe3O4(s) + CO(g) ΔH° = -18.0 kJ

FeO(s) + CO(g) → Fe(s) + CO2(g) ΔH° = -11.0 kJ

Fe2O3(s) + 3CO(g) → 2Fe(s) + 3CO2(g) ΔH° = -23.0 kJ

Calculate ΔH° for the reaction: 3Fe2O3(s) + CO(g) → 2Fe3O4(s) + CO2(g)

Python

1. Change the order of an input string based on Unicode equivalent.

Write a function Reorder that will take an input string of a maximum length of 20 characters and create a new string that reorders the string based on it’s binary Unicode character equivalent, e.g. ‘a’ = 0x61, ‘A’ = 0x41, from smallest value to largest value. In this example, ‘A’ would come before ‘a’, as 0x41 is a smaller number than ox61. Note, use python logical operators to do the comparison. Do not try to create a Unicode lookup table. For your code, use the string “sum=(x*259)/average” as your input string to your function.

Regional trading blocs, such as the European Union (EU) and NAFTA, are growing in importance. Why do you think this is so - what do countries gain from joining a regional trading bloc? What the implications of these trading blocs for international business? Are they helpful or harmful? How might they affect a firm's investment decision?

Bilboa Freightlines, S.A., of Panama, has a small truck that it uses for intracity deliveries. The truck is worn out and must be either overhauled or replaced with a new truck. The company has assembled the following information:

If the company keeps and overhauls its present delivery truck, then the truck will be usable for five more years. If a new truck is purchased, it will be used for five years, after which it will be traded in on another truck. The new truck would be diesel-operated, resulting in a substantial reduction in annual operating costs, as shown above.

The company computes depreciation on a straight-line basis. All investment projects are evaluated using a 13% discount rate.

Click here to view Exhibit 13B-1 and Exhibit 13B-2, to determine the appropriate discount factor(s) using tables.

Required:

1. What is the net present value of the “keep the old truck” alternative?

2. What is the net present value of the “purchase the new truck” alternative?

3. Should Bilboa Freightlines keep the old truck or purchase the new one?

What would be the effect of each of the following sources of error in the reaction between Mg and HCl? Would they result in a high, low, or unaffected value for the heat of reaction? Why?

A. The calorimeter absorbs heat.
B. The thermometer reads 2 °C low at all temperatures.
C. The actual molarity of the HCl is slightly higher than reported on the bottle.

D. The mass of the filter paper was not subtracted in the determination of ∆H1.

The following data were taken from the financial statements of Hunter Inc. for December 31 of two recent years:

Explain what evolutionary adaptations, in general, exist in hyperthermophilic bacteria in terms of their cell membranes and cellular proteins. Your answer should explain how such adaptations provide advantages in terms of protein and membrane function at extremely high temperatures.
