Choose the response that lists the member of each of the following pairs that has the higher boiling point. (I) H2O or KI       (II) HF or HI      (III) Cl2 or Br2

0.204 g of an unknown compound dissolved in 180 mL of water has an osmotic pressure of 26.2 mmHg at 24.0°C.  Calculate the molar mass of the compound. (R = 0.0821 L·atm/K·mol)

For the reversible reaction SO2(g) + NO2(g)   ↔   SO3(g) + NO(g), the equilibrium constant is 18.0 at 1,200ºC.  If 1.0 mole of SO2 and 2.0 moles of NO2 are placed in a 20 L container, what concentration of SO3 will be present at equilibrium?

A 0.10 M NH3 solution is 1.3% ionized.  Calculate the H+ ion concentration.             NH3 + H2O → NH4+ + OH–

What is the osmotic pressure of a solution that contains 16.2 g of propyl alcohol (C3H7OH) dissolved in enough water to make 400 mL of solution at 27°C?

What is the molality of a solution that is 6.72 % by mass calcium chloride?

Calculate the standard enthalpy change for the reaction    2C8H18(l) + 17O2(g) ->16CO(g) + 18H2O(l).             Given: 2C8H18(l) + 25O2(g) -> 16CO2(g) + 18H2O(l)    Δ{“version”:”1.1″,”math”:”Δ”}H° = –11,020 kJ/mol 2CO(g) + O2(g) -> 2CO2(g)                              Δ{“version”:”1.1″,”math”:”Δ”}H° =   –566.0 kJ/mol

This quiz has a time limit of 17 minutes which includes 2 minutes to answer the questions 15 minutes to scan and upload your “work packet”   It is your responsibility to watch the time (see upper right corner) and use the last 15 minutes to scan and upload your work packet.  You can use the timer below to alert you to stop working and scan. Changes to quiz responses or the work packet are not permitted once scanning begins. If you finish before the working time passes, please be sure to check/finalize your responses before beginning the scanning process. If you have questions during this quiz, you can give me a call at 805-592-9895.  (If I don’t answer it’s because I am on a call with one of your classmates.  Leave me a message and I will call you back.)
