Mоdule 2 Summаtive Assessment Questiоn: (35 pts) Describe the mоleculаr shаpe and polarity of the nitrate ion (NO3-): Write out electron configurations for each element in the ion. (5 pts) Draw orbital diagrams for each of the electron configurations you wrote to determine the number of unpaired electrons present for each element. (5 pts) Calculate the total number of valence electrons for the molecule/ion. (2.5 pts) Complete a Lewis structure for the molecule/ion showing ALL lone pair electrons, multiple bonds, and resonance structures, if necessary. (7.5 pts) Once your Lewis structure(s) is/are completed, determine and label formal charges for each atom. Hint: This can be used as a double-check that you did your Lewis structure(s) correctly. (5 pts) Dipole Moment: (5 pts) Draw bond dipoles (if present) Determine the overall dipole moment for the molecule (if present) Draw arrow pointing the correct direction next to your Lewis structure(s) (if present) Re-draw your Lewis structure as a 3D representation of the molecular shape, name the electron pair geometry and molecular geometry/shape of the molecule/ion. (5 pts) For Parts 4-7 do your best to describe your drawings in word form. I will create a separate spot that you can submit photos of your work for the whole exam so I can better distribute partial credit.

Use the clаss diаgrаm belоw tо create a new class called FreshDrink. This class will be used tо store the details of Fresh Drinks ordered. The class diagram below indicates the properties and methods of the class. FreshDrink Properties: — itemCode : string— itemName : string— price : real— quantity : integer— itemCategoryType : integer+ JUICE = 1 : integer+ SMOOTHIE = 2 : integer+ HOTDRINK = 3 : integer Methods: + Constructor(iC : string, iN : string, p : real, q : integer, iCat : integer)+ getCategoryType() : String;+ getItemCode() : integer+ getprice() : string+ getQuantity() : integer+ getTotalPrice() : real+ getDiscount() : real+ toString() : string 3.1 Create a new class named FreshDrink. [1] 3.2 Write code to create five properties to store itemCode, itemName, price, quantity and itemCategoryType. Choose appropriate data types for these attributes. These properties should not be visible from outside the class. [3] 3.3 Write code to create the three static/class constants JUICE with the value 1, SMOOTHIE with the value 2 and HOTDRINK with the value 3 [3] 3.4 Create a constructor method that accepts a string iC as a parameter representing the itemCode, a string iN as parameter representing the itemName, a real value p as parameter representing the price, an integer q as parameter representing the quantity and an integer iCat as parameter representing the itemCategoryType. Use these parameters to assign values to the properties. [2] 3.5 Write code to create a method called getCategoryType that returns the name of the item category type depending on the value of the itemCategoryType property. ● If the itemCategoryType property has the same value as JUICE, the method should return “Juice” ● If the itemCategoryType property has the same value as SMOOTHIE, the method should return “Smoothie” ● If the itemCategoryType property has the same value as HOTDRINK, the method should return “Hot drink” [3] 3.6 Create accessor/get methods for the itemCode, price and quantity properties. [1] 3.7 Write code to create a method named getTotalPrice(). This method should return the price multiplied by the quantity. [2] 3.8 Write code that will create a toString method that will return a string representation of a FreshDrink instance in the following format: itemName itemCodeitemType quantitypricetotal price Example: Blueberry:BLU05 Juice, 2 @ R40 Total: R80 [4]
1.1 Write а query thаt will displаy all the FreshDrinks sоrted alphabetically by the drink names. The first five recоrds оf the result are shown in Source E. [3] 1.2 Display the average price of drinks per category sorted from highest to lowest average cost. Use the heading: AveragePrice. Source F shows the result of the query. [4] 1.3 Write a query that will display all customers who are under the age of 18 and require consent from a guardian to make online purchases. The query should display the name, surname and age of the customer. Source G shows the result of the query. [8] 1.4 Write a query that will display the dateOfSale and the TotalSales amount per day where the TotalSales figure was more than R200. Source H shows the result of the query. [8] 1.5 Write a query that will display all the sales made in the month of April showing the date of sale, customer surname and name, the drink name and the total for the sale. Sort the list by the date of sale. The first five records of the result are shown in Source I. [6] 1.6 Write a query that will display all the drinks that are above the average cost of all the drinks combined. Source J shows the result of the query. [5] 1.7 The price of all FreshDrinks that are under R20 was incorrectly typed into the database. Change these values to R30. [3] 1.8 Insert a new FreshDrink item called "Kiwi Fountain” with itemCode"KWI303" in the FreshDrink table. This FreshDrink has the same category and cost as the “Banana Java” FreshDrink. Only the FreshDrink name and code may be hardcoded. [8] 1.9 Some customers registered online but have not purchased any FreshDrinks yet. Write a query to display a list of all the customers who have not yet ordered any FreshDrink online. Source K shows the result of the query. [5]
