The C₅H₅⁺ and C₅Cl₅⁺ cations, which have never been isolated, are known to be ground state triplets - that is, they have 2 unpaired electrons, thus are diradicals. But the C₅(CH₃)₅⁺ cation has no unpaired electrons - it is a singlet.

Construct a schematic molecular diagram of C₅H₅⁺ (pi system only) in D₅h point group using p_z-orbitals of C. Sketch the shape of each orbital next to the irreducible representation of the MO. Does your MO diagram support the singlet or triplet ground state?

Result from X-ray crystallography, NMR, and theory..... C₅(CH₃)₅⁺ is an irregular pentagon.... the ring is nonplanar... the pi electrons are found to be largely localized on opposite sides of the ring - in an allyl cation fragment and in a double bond.

Now, construct a schematic molecular diagram of C₅(CH₃)₅⁺ (pi system only) using p_x-orbitals of C, assuming allyl group and a double bond separately and simply put them on the same stack). Sketch the shape of each orbital next to the irreducible representation of the MO. Does your MO diagram support the singlet or triplet ground state?

Please help!! Super hard homework question!

A gymnast of mass 62.0kg hangs from a vertical rope attached to the ceiling. You can ignore the weight of the rope and assume that the rope does not stretch. Use the value 9.81m/s2 for the acceleration of gravity.

Calculate the tension T in the rope if the gymnast hangs motionless on the rope.

Calculate the tension T in the rope if the gymnast climbs the rope at a constant rate.

Calculate the tension T in the rope if the gymnast climbs up the rope with an upward acceleration of magnitude 1.20m/s2 .

Calculate the tension T in the rope if the gymnast slides down the rope with a downward acceleration of magnitude 1.20m/s2 .

Sharp Company manufactures a product for which the following standards have been set:

During March, the company purchased direct materials at a cost of $45,210, all of which were used in the production of 2,500 units of product. In addition, 4,100 direct labor-hours were worked on the product during the month. The cost of this labor time was $30,750. The following variances have been computed for the month:

Required:

1. For direct materials:

a. Compute the actual cost per foot of materials for March.

b. Compute the price variance and the spending variance.

2. For direct labor:

a. Compute the standard direct labor rate per hour.

b. Compute the standard hours allowed for the month’s production.

c. Compute the standard hours allowed per unit of product.

Questions

Which fuel was more efficient (produced more calories per gram)? Explain your answer. Fuel canister: (diethylene glycol) or Tea candle: (paraffin) ?

Explain the difference in the efficiencies of the fuels you tested based on the chemical structures of the fuels.

Conduct research on both diethylene glycol and paraffin wax; for each fuel, summarize in your own words in one or two sentences how these fuels are synthesized. Cite the sources that you use for your research.

In the 1990 Clean Air Act Amendments, Congress and the EPA rely on the automobile industry to develop a cleaner automobile. At the same time, the government imposes a relatively minor federal tax on gasoline. a. Do you see any problem with the implicit signals the federal government is sending to American auto manufacturers and to American car drivers through these policies? Briefly discuss. b. Formulate a hypothetical economic policy to motivate automobile manufacturers to advance the technology of cleaner motor vehicles.

Show that a satellite may speed down: that is, show that if frictional forces or reverse thrust cause a satellite to lose total energy, it will move into an orbit closer to the earth and may have increased kinetic energy.

What is the difference between a parameter and a statistic? Describe an example. Finally, there are “adjustments” that statisticians make to statistics to make them better represent the parameter, discuss what this looks like with the standard deviation.

1. When 4.203g of NaOH is added to 100.0mL of water, the temperature of the solution increases by 3.0C. Assume the density of the solution to be 1g/mL and the specific heat of capacity of the solution to be 4.184 J/gK.

a) Calculate the amount of heat absorbed by the solution.

b) Find the enthalpy change for the dissolution of NaOH.

c) Find the enthalpy change per mole of NaOH.

“It is better to pay regular price than to stand in a long line for a free item.” Discuss the statement using three (3) core principles of economics (with applicable examples) to support your views.

You prepare a buffer solution from 10.0 mL of 0.100 M MOPS (3-morpholinopropane-1-sulfonic acid) and 10.0 mL of 0.084 M NaOH. Next, you add 1.00 mL of 4.69 × 10-6 M lidocaine to this mixture Denoting lidocaine as L, calculate the fraction of lidocaine present in the form LH .
The Ka of MOPS is 6.3 e-8, and the Kb of lidocaine is 8.7e-7

Write a Python program that uses while loops to perform the following steps and post the text code. Thanks

a. Prompt the user to input two positive integers (no zero or negative). variables: firstNum and secondNum (firstNum must be less than secondNum). Validate the user's input; prompt the user again if firstNum is not less than secondNum (use while loop).

b. Output all odd numbers between firstNum and secondNum. (use while loop).

c. Output the sum of all even numbers between firstNum and secondNum. (use while loop).

d. Output the sum of the square of the odd numbers between firstNum and secondNum. (use while loop)

Program layout for each step:

#A

while loop

#B

***Allow the user to repeat the program. (requires another while loop).

***Do NOT define any functions.

***Your program output must be exactly the same as the output in the OUTPUT section, except font style.

OUTPUT:

- The bold text is the user's input.
