Submit your Python script file in the posting of your assignment. Your Python script should be either a .txt file or a .py file.




You must execute your script and paste the output produced into a document that you will submit along with your Python script.




It is very helpful if you print a placeholder between the printing of 9 lines and the printing of 25 lines. It will make your output easier to read for your peer assessors. A placeholder can be output such as “Printing nine lines” or “Calling clearScreen()”.




The following items will be used in the grading rubric for this assignment. Make sure that you have addressed each item in your assignment.





Does the assignment implement new_line, three_lines, nine_lines, and clear_screen functions, as well as a main section of the program which calls the functions?





Calculate the H3O+ concentration for each pH.

pH=11[H3O+]= 

pH=2[H3O+]= 

pH=5[H3O+]=


Complete these Brønsted–Lowry reactions.


HCO−3+H+↽−−⇀


HCO−3+OH−↽−−⇀


Complete and balance the three equations according to acid and base behavior in water. Phase labels are optional.


HNO3(aq)+H2O(l)⟶


Ba(OH)2(s)−→−−H2O


HF(aq)+H2O(l)↽−−⇀


Write a function in this file called nine_lines that uses the function three_lines (provided below) to print a total of nine lines.








Now add a function named clear_screen that uses a combination of the functions nine_lines, three_lines, and new_line (provided below) to print a total of twenty-five lines. The last line of your program should call first nine_lines and then the clear_screen function.








The function three_lines and new_line are defined below so that you can see nested function calls. Also, to make counting “blank” lines visually easier, the print command inside new_line will print a dot at the beginning of the line:








def new_line():








print('.')








def three_lines():









new_line()








new_line()









































Give the name for the acid with the formula H3PO4 .


Mr. A and Mr. B have the following respective demands


Pa= 25- 5X

Pb= 11- X

a. Graph them on separate graphs

b. Mr A has no X's while Mr. B has 10 X's. What are the marginal and total values at this quantity? Using either method discussed in the chapter, determine how much each will have after trade? What will be their marginal values at this quantity?
