Concept Check: (WCSP25) a. The concentration of an aqueous solution when water is removed by evaporation.  b. A 2.0 M solution of calcium hypochlorite, Ca(ClO)2, has a M concentration of ClO- ions. c. Consider a chemical reaction in which strong bonds are formed and weak bonds are broken. The heat of the reaction is . d. A reducing agent electrons in a chemical process.  e. The limiting reactant is in a chemical reaction. f.  When 5.0 g of KClO4 was dissolved in a solution, the temperature of the solution decreased by 1.76  ̊C. The heat of solution (ΔHsoln) for KClO4 is . g. Select the salt that would form a precipitate when mixed with CuSO4:

In this part, you will write the implementation of the method below. Your implementation should be consistent with the class you’ve written in a prior step (i.e., only use the field(s) and method(s) that exist in the MyBookingScheduler class). You do not need to include any import statements or Javadoc comments in your response. T cancel(T booking) throws IllegalArgumentException, NoSuchElementException Removes and returns the booking in the system that is equal to the booking passed in. Remaining bookings should be shifted towards the beginning of the system. This method MUST use the cancel(int index) method to perform the removal! HINT: The implementation of this method is simple if you’ve implemented the cancel(int) and indexOf(T) methods. Think about how you can use these two methods to find and remove a booking that is equal to the argument (and throw the required exceptions, if necessary).  You can also rely on the propagation of exceptions, where appropriate. Method throws IllegalArgumentException when the reference passed in for the booking is null. The message should contain text describing the specific reason the argument is illegal. You may assume that IllegalArgumentException is an unchecked exception and has a constructor that takes in a single String parameter representing the message. Method throws NoSuchElementException when a booking equal to the argument doesn’t exist within the system. The message should contain text describing the specific reason the argument is illegal. You may assume that NoSuchElementException is an unchecked exception and has a constructor that takes in a single String parameter representing the message. Make sure to select the ‘Preformatted’ style from the dropdown so your code is formatted clearly. DO NOT USE THE TAB KEY WHEN WRITING CODE AS YOU MAY ACCIDENTALLY SUBMIT YOUR EXAM.
