A 74-year-old male with a PMH significant for 50-pack-year cigarette use, presents for evaluation of worsening cough and one episode of hemoptysis.  Other than nicotine stains present on his left index and middle fingers, his physical examination is unremarkable.  CXR reveals a 4 cm. right lung mass.  Serum sodium is 125 mEq/L (↓), BUN 12 mg/dL, creatinine 1.1mg/dL. Serum osmolality is 260 mOsm/L (↓), and urine sodium is 50 mEq/L (↑).  The patient’s mucous membranes are moist, skin turgor is normal, and he does not demonstrate orthostatic change in BP.  He currently takes no prescription or OTC medications or supplements.  TSH level is normal.  Based on this information, which of the following conditions is the most likely etiology of this patient’s hyponatremia?

We have discussed several relationships between variables in the ideal gas law.  Choose a pair of variables, give their relationship and provide a molecular-level description about why this is true.  (Assume other variables to be constant.). (WCSP25)   Boyle’s Law P and V Charles’ Law V and T Avogadro’s Law n and V

Concept Check: (WCSP25) a. The concentration of an aqueous solution [drop1] when water is removed by evaporation.  b. A 2.0 M solution of calcium hypochlorite, Ca(ClO)2, has a [drop2] 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 [drop3]. d. A reducing agent [drop4] electrons in a chemical process.  e. The limiting reactant is [drop5] 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 [drop6]. g. Select the salt that would form a precipitate when mixed with CuSO4: [drop7]

For which of the following reactions would ΔHf = ΔHrxn for the formation of HCl? (WCSP25)  

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. int bookingCount() Returns number of bookings currently in the system. HINT: the booking count of the system isn’t the same as the length of the backing array. You’ll want to keep track of the logical count of the collection using a private field. 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. USE THE SPACE BAR INSTEAD.

What will be the output of the following program? class Counter { int count = 0; public synchronized void increment() { count++; } } public class Test { public static void main(String[] args) throws InterruptedException { Counter c = new Counter(); Thread t1 = new Thread(() -> { for (int i = 0; i < 1000; i++) c.increment(); }); Thread t2 = new Thread(() -> { for (int i = 0; i < 1000; i++) c.increment(); }); t1.start(); t2.start(); t1.join(); t2.join(); System.out.println("Count: " + c.count); } }
