Carbonyl fluoride, COF2, is an important intermediate used in the production of fluorine-containing compounds. For instance, it is used to make the refrigerant carbon tetrafluoride, CF4 via the reaction

2COF2(g)⇌CO2(g)+CF4(g),    Kc=7.40

If only COF2 is present initially at a concentration of 2.00 M, what concentration of COF2 remains at equilibrium?

Where I get stuck is figuring out how to multiply (x)(x)/ (2.00-2x)^2 I know this is easy math but can you please work it out step for step so that I can see exactly how you go the answer.

In order to complete these exercises, you will need to install prolog from swi-prolog.org.

Write a Prolog program by creating a file with you favorite program editor like Notepad++ that contains the following facts:

• here the predicate parent(X,Y) means X is the parent of Y

• you can also copy/paste or download the following database from the

  course website

  female(pam). female(liz). female(ann). female(pat). male(tom). male(bob). male(jim). parent(pam,bob). parent(tom,bob). parent(tom,liz). parent(bob,ann). parent(bob,pat). parent(pat,jim).

  (a) Load this file into Prolog, usually this is done with the consult file predicate: ?- consult(‘<filename>’).

  On Windows you can load the fact database with the menu point File®Consult.
  also overloads a bare string list by consulting each item in the list: ['family_tree.pl'].

• % these are the family facts
  female(pam).
  female(liz).
  female(ann).
  female(pat).
  male(tom).
  male(bob).
  male(jim).
  parent(pam,bob).   % pam is parent of bob (etc.)
  parent(tom,bob).
  parent(tom,liz).
  parent(bob,ann).
  parent(bob,pat).
  parent(pat,jim).

  will work. Once you have loaded the program pose the following queries:

  ?- female(ann).
  ?- female(jim).
  ?- parent(X,bob).
  ?- parent(tom,X).
  ?- parent(X,ann),parent(X,pat).

  What are the answers to these queries? Beware, for some queries here might be more than one answer. To get all the answers type a ';' and carriage return at the question mark.

  (b) Now, using the parent predicate formulate the following Prolog queries:

  1. Who is Pat's parent?
  2. Does Liz have a child?

SWI-Prolog

3. Who is Pat's grandparent?

(c) Given the above facts, extend the program by writing rules defining the following predicates:

sister(X,Y) -- X is the sister of Y.
son(X,Y) -- X is the son of Y.
father(X,Y) -- X is the father of Y. grandmother(X,Y) -- X is the grandmother of Y. ancestor(X,Y) -- X is an ancestor of Y.

(Hint: this predicate might come in handy: different(X,Y):- not(X=Y). Some predicate definitions might be recursive.)

Add these rules to your existing file and attach the file to your submission

Demonstrate that your program works by posing the following queries:

4. ?- sister(X,pat).
5. ?- sister(X,Y).
6. ?- son(jim,X).
7. ?- father(X,bob).
8. ?- grandmother(X,ann). 9. ?- ancestor(X,jim).

Hand in the source code of your prolog program and a proof of the program execution.

For each of parts a, b, and c, you should include screenshots of the relevant contents of the SWI-Prolog console. Part c additionally requires you to attach your .pl file.

The contribution format income statement for Huerra Company for last year is given below:

The company had average operating assets of $495,000 during the year.

Required:

1. Compute the company’s return on investment (ROI) for the period using the ROI formula stated in terms of margin and turnover.

For each of the following questions, indicate whether the margin and turnover will increase, decrease, or remain unchanged as a result of the events described, and then compute the new ROI figure. Consider each question separately, starting in each case from the data used to compute the original ROI in (1) above.

2. Using Lean Production, the company is able to reduce the average level of inventory by $104,000. (The released funds are used to pay off short-term creditors.)

3. The company achieves a cost savings of $6,000 per year by using less costly materials.

4. The company issues bonds and uses the proceeds to purchase machinery and equipment that increases average operating assets by $126,000. Interest on the bonds is $13,000 per year. Sales remain unchanged. The new, more efficient equipment reduces production costs by $7,000 per year.

5. As a result of a more intense effort by sales people, sales are increased by 25%; operating assets remain unchanged.

6. At the beginning of the year, obsolete inventory carried on the books at a cost of $19,000 is scrapped and written off as a loss.

7. At the beginning of the year, the company uses $184,000 of cash (received on accounts receivable) to repurchase and retire some of its common stock.

2. A complex number can be expressed as a + bi where a and b are real numbers and i is the imaginary unit. The multiplication of two complex numbers is defined as follows:

(a+bi)(c+di) = (ac-bd) + (bc+ad)i

Define a class which represents a complex number. The only member functions you have to define and implement are those which overload the * and *= symbols.

In C++ please, thank you

1. Design and implement a class called RandomArray, which has an integer array. The constructor receives the size of the array to be allocated, then populates the array with random numbers from the range 0 through the size of the array. Methods are required that return the minimum value, maximum value, average value, and a String representation of the array values. Document your design with a UML Class diagram. Create a separate driver class that instantiates a RandomArray object and outputs its contents and the minimum, maximum, and average values.

Write an error-free Python program to do the following things.

• The program should prompt the user to input a sequence of numbers (say population of states) and then displays the numbers as a bar chart using asterisks.  

• The numbers must be stored in a list. There will be 6 numbers in total.

• Write a functionto display the output. The program needs to pass the list of numbers to the function and the output is done in the function.  

Sample output:

Enter population for state 1: 5

Enter population for state 2: 4.5

Enter population for state 3: 3

Enter population for state 4: 7

Enter population for state 5: 6

Enter population for state 6: 2

Elixir Corporation has just filed for bankruptcy. Elixir is a holding company whose assets consist of real estate worth $240 million and 100% of the equity of its two operating subsidiaries. It is financed partly by equity and partly by an issue of $560 million of senior collateral trust bonds that are just about to mature. Subsidiary A has issued directly $480 million of debentures and $31 million of preferred stock. Subsidiary B has issued $260 million of senior debentures and $140 million of subordinated debentures. A’s assets have a market value of $580 million and B’s have a value of $316 million. How much will each security holder receive if the assets are sold and distributed strictly according to precedence?

Payoff: (I can't seem to figure out the correct amount for the trust bond)

a. Debenture = 480 million

b. Senior debenture = 260 million

c. Subordinated debenture = 56 millio

d. Trust bond= ?

e. Preferred stock = 31 million
