Given the data below, what is the standard free energy for the reaction B2H6(g) + 3Cl2(g) = 2BCl3(g) + 3H2(g) in kJ/mol? While exact sig figs are not required, please be careful with them: the answer is accurate to the tenths place. Answer in kJ/mol. Do not use scientific notation. Do not type units. Standard Free Energy of Formation Compound

cumulative The pKa of 2-methylpyridine (H7C6N) is 5.95. What is the pH of the buffer made from 0.41 mol 2-methylpyridine and 0.93 mol sodium 2-methylpyridinium (the conjugate acid of 2-methylpyridine) dissolved to make a 500.00 mL solution? Exact sig figs required. Do not use scientific notation.

A system initially has 24 states. Select all the final state values that will result in a non-spontaneous reaction. You may select more than one. The instructor suggests you try out each in your calculator.

Cumulative. Doubling the concentration of a reactant has no effect on the reaction rate. What is the order of the reactant? (0 for zeroth, 1 for first, etc.)

Describe the process we followed for extracting DNA from strawberries in class.  The more detail you provide, the more points you’ll be awarded.

A 78-year-old male presents with lower abdominal discomfort, difficulty initiating urination, and a sensation of incomplete bladder emptying. On examination, his abdomen is distended and firm over the suprapubic area. A bedside bladder scan shows 850 mL of retained urine. Which of the following is the most appropriate initial management?

While teaching a postoperative abdominal surgery patient how to use incentive spirometry, the respiratory therapist should explain that the primary purpose of this therapy is to do what?
