Companies A and B face the following interest rates (adjusted for the differential impact of taxes):

Assume that A wants to borrow U.S. dollars at a floating rate of interest and B wants to borrow Canadian dollars at a fixed rate of interest. A financial institution is planning to arrange a swap and requires a 50-basis-point spread. If the swap is equally attractive to A and B, what rates of interest will A and B end up paying?

Explain in detail.

Select True or False depending on whether the corresponding statement is true or false. 1. Let z1 be a z− score that is unknown but identifiable by position and area. If the area to the right of z1 is 0.8413, the value of z1 is 1.0 2. The mean and standard deviation of an exponential random variable are equal to each other. 3. Using the standard normal curve, the z−score representing the 90th percentile is 1.28. 4. A random variable X is normally distributed with a mean of 150 and a variance of 36. Given that X=120, its corresponding z− score is 5.0

At 25C, calculate:

a) ∆G˚ for the reaction, given that: ∆Gf Zn(s) = 0, ∆Gf(H+) = 0, ∆Gf(H2) = 0, ∆Gf(Zn2+) = -147.1 kj/mol

b) ∆G, when P(h2) = 750 mmHg, [Zn2+ aq] = 0.10 M, [H+] = 1.0 x 10^-4 M

c) The pH when ∆G - -100 kJ, P(h2) = 0.922 atm, [Zn2+] = 0.200 M and the mass of Zn is 155 g.

An elementary reaction A to B is reversible and has an equilibrium constant of 10, and a forward rate constant of 1.0 d^-1.

a) Plot the concentrations of A and B as a function of time in a batch reactor that initially contains 10^-3 M each of A and B. Show the data from the initial condition until the concentrations are both changing at an instantaneous rate of less than 10^-5 M per day.

b) Repeat part (a) if the initial concentrations are 2 x 10^-3 M of A and no B.

c) What are the molar concentrations of A and B at equilibrium in part (b)?

you want to make 100ml of 0.20M acetic acid buffer with pH=50. you are given a stock of 1.0M acrtic acid and a bottle of solid sodium acetate sale (MW=82g/mol).
what is the ratio of [A-]/[HA] when your buffer pH is 5.0?
determine the concentration of weak acid and conjugate base in the buffer.
how many mL of 1.0 acetic acid will you need?
how many grams of sodium acetate will you need?
if you now have add 1mL of 1M NaOH to your buffer, what would be the resulting pH?

What is the barrier to rotation about the C-C bond in ethane?

                A. about 1.0 kcal/mol                      B. about 3.0 kcal/mol

                C. about 2.0 kcal/mol                      D. about 2.5 kcal/mol

A.    Trans methyl groups favor chair and both are equatorial.

B.     Trans methyl groups favor chair and both are axial.

C.     Trans methyl groups favor twist-boat conformation.

D.    Trans methyl groups favor chair and are axial and equatorial.

A ballerina does a spin. a) Strating from rest, she accelerates to an angular velocity of 15.7 radians per seconds in 1.2 seconds. she maintains velocity for 1.0 more seconds. How far does she turn in total? Give your answer in number of rotation

b) As she spins she is balanced on an area of her shoe with diameter 3.0cm. Here center of gravvity is located 2.5 feet above the ground and in the equilibrium postion is centered horizontally. How far can she tilt before she will fall over?  

Using design theory:

construct a difference aplifier that meets the following design equation: V0=2Vb-4Va. You must use resistor values that range from 200 Ohms - 50k Ohms. The rail voltage must be +- 12V.

Use your design equations to determine the output voltage Vo for the following input cases:

1. Va= 1.0V DC, Vb= 2V DC

2. Va=Vb=1.0 Vpp 1 kHz sinusoidal voltage

3.Va=Vb=3.0 Vpp 1kHz triangular waveform voltage

Recall that a float is stored in the following format:

±sign 1.mantissa • 2^exponent?127

where sign is 1 bit, exponent is 8 bits, and mantissa is 23 bits. Write a C function that accepts an int parameter and returns a float represented by the bits in the int. The 32-bit integer is organized as 1-bit sign, 8-bit exponent, 23-bit mantissa. For example, 0x3F800000 represents 1.0 because the sign bit is 0, the exponent is 127, and the mantissa is all 0’s.

It has to be a proper c executable code.Please help.
