- You are a Chemistry major who has to create a program for first time chemistry lab users.
- The Erlenmeyer flask contains a nitric acid solution.
- When the student presses a button, 0.5 mL of NaOH solution can be added to a buret, which is set up over the Erlenmeyer flask.
- An indicator is added to the solution being titrated. The indicator is a substance that changes to blue when the reaction is complete (endpoint). You determine the amount of mixture that will cause this reaction to occur.
- Create a titration simulator that will allow a student to add up to 18 mL of titrant. Notify the student when the mixture turns blue.
In Python please :)

- The description is in the photoread carefully the question and answer properly subject software engineering language C++ Question Suppose a company wants to develop software for an alarm clock. The clock shows the time of day. Using buttons, the user can set the hours and minutes fields individually, and choose between 12 and 24-hour display. It is possible to set one or two alarms. When an alarm fires, it will sound some noise. The user can turn it off, or choose to ‘snooze’. If the user does not respond at all, the alarm will turn off itself after 2 minutes. ‘Snoozing’ means to turn off the sound, but the alarm will fire again after some minutes of delay. This ‘snoozing time’ is pre-adjustable. Draw state machine diagram for the above scenario. Draw State Chart diagram for the above scenario.The Westfield Carpet Company has asked you to write an application that calculates theprice of carpeting for rectangular rooms. To calculate the price, you multiply the area of thefloor (width times length) by the price per square foot of carpet. For example, the area offloor that is 12 feet long and 10 feet wide is 120 square feet. To cover that floor with carpetthat costs $8 per square foot would cost $960. (12 3 10 3 8 5 960.)First, you should create a class named RoomDimension that has two fields: one for the lengthof the room and one for the width. The RoomDimension class should have a method thatreturns the area of the room. (The area of the room is the room’s length multiplied by theroom’s width.)Next you should create a RoomCarpet class that has a RoomDimension object as a field. Itshould also have a field for the cost of the carpet per square foot. The RoomCarpet classshould have a method that returns the total cost of the carpet.Figure 8-21 is a UML diagram that shows…
- Instructions Objectives: Use a while loop Use multiple loop controlling conditions Use a boolean method Use the increment operator Extra credit: Reuse earlier code and call two methods from main Details:This assignment will be completed using the Eclipse IDE. Cut and paste your code from Eclipse into the Assignment text window. This is another password program. In this case, your code is simply going to ask for a username and password, and then check the input against four users. The program will give the user three tries to input the correct username-password combination. There will be four acceptable user-password combinations: alpha - alpha1 beta - beta1 gamma - gamma1 delta - delta1 If the user types in one of the correct username-password combinations, then the program will output: “Login successful.” Here are a couple of example runs (but your code needs to work for all four user-password combinations): Username: betaType your current password: beta1Login…Using C# in Microsoft Visual Studio create an application that lets the user play the game of Rock, Paper, Scissors against the computer. The program should work as follows:1. When the program begins, a random number in the range of 1 through 3 is generated. If the number is 1, then the computer has chosen rock. If the number is2, then the computer has chosen paper. If the number is 3, then the computer has chosen scissors. (Do not display the computer’s choice yet.)2. The user selects his or her choice of rock, paper, or scissors. To get this input you can use Button controls, or clickable PictureBox controls displaying some of the artwork that you will find in the student sample files.3. The computer’s choice is displayed.4. A winner is selected according to the following rules:• If one player chooses rock and the other player chooses scissors, then rock wins. (Rock smashes scissors.)• If one player chooses scissors and the other player chooses paper, then scissors wins. (Scissors…Active buzzer project.

The billboard will have two steel supports, one on each side. The height of each steel bracket must be equal. You have a number of rebar rods that can be welded together. For example, if the bars are of length 1, 2, and 3, they can be welded together to form a length of 6 brackets. Return the maximum possible installation height of the billboard. Return 0 if the billboard cannot be installed.Reza Enterprises sells tickets for buses, tours, and other travel services. Because Reza frequently mistypes long ticket numbers, Reza Enterprises has asked his students to write an application that shows if a ticket is invalid. Your application/program tellsthe ticket agent to enter a six-digit ticket number. Ticket numbers are designed so that if you lose the last digit of the number, then divide by 7, the remainder of the division is exactly the same to the last dropped digit. This process is shown below: Step 1: Enter the ticket number; for example 123454 Step 2: Remove the last digit, leaving 12345 Step 3: Determine the remainder when the ticket number from step 2 is divided by 7. In this case, 12345 divided by 7 leaves a remainder of 4. Step 4: Display a message to the ticket agent indicating whether the ticket number is valid or not.. Test your application with the following ticket numbers: - 123454; is a valid ticket number - 147103; is a valid ticket number -…
- In Lab 2, you created a menu for a simple calculator program. In this lab, you will add some functionality to the menu. Also, it is important to let the user know if they entered an invalid choice. Write a program (or modify the one written for Lab 2) that displays the following menu and prompts the user for a selection. Once the selection has been made, display the selection back to the user. Then, ask the user for two numbers and perform the selected operation (+, -, *, /). Display the results back to the user (e.g. 2 + 3 = 5). When dividing, display an error message if the second number (denominator) is 0. 1) Add two numbers 2) Subtract two numbers 3) Multiply two numbers 4) Divide two numbers 9) Exit program The program should: contain header comments as shown in class display a "hello" message before presenting the menu display the menu prompt the user for selection display the selection back to the user if the selection was invalid, display error message to user and then go…For this lab, you will be doing the following in C#: 1) Create a Home form with buttons that when clicked, will open the Account, Email, and eventually the Contact forms. The Account form should be opened in "View" mode. 2) Add code to the Login form so the Account form opens when the user clicks "Create New Account". The Account form should be opened in "Modify" mode. 3) Add code to the Login form that validates the user input before allowing the user the access the Home form. For now, just verify the user enters "user1" and "12345" for the username and password respectively.What may happen if you hovered the mouse over an unstable section of code for too long?
