Which intermolecular force is present in ALL molecules?

Dispersion

100

What is the overall order of the following rate law? Rate = k[A][B]2

third order

100

What is the pOH of a 0.07M NaOH solution?

pOH = 1.15

100

Does the following reaction gain or lose entropy?

NH3(l) → NH3(g)

Gain -- going from a liquid to a gas.
200

What is the strongest intermolecular force in the following molecule: NH3?

Hydrogen-bonding

200

If you double the concentration of A, what is the effect on the overall rate? 

Rate = k[A]2[B]

Rate is quadrupled (x4)

200

If a solution has a pH = 3.9, what is the [H3O+]?

1.26 x 10-4M 

200

What did Dr. Hoober work on for her Ph.D?

She worked on batteries for grid-scale energy storage.

300

What is the molarity of a 62g (MW = 180g/mol) glucose solution in 560mL water (MW = 18g/mol)?

0.62M

300

If Q > K for a reaction, in which way does the reaction shift to reestablish equilibrium?

It shifts left (towards the products)

300

What are the seven strong acids?

HNO3, HSO4, HBr, HI, HClO4, HClO3, HCl

300

In a voltaic cell, where does oxidation occur in the battery?

The anode!

400

What is the molality of a 62g glucose solution (MW = 180g/mol) in 130g H2O (MW = 18g/mol)?

2.65m

400

If a reaction has H = 178J/mol, under what conditions would you expect the greatest yield of products? (Think about temperature and pressure)

High temperature, high pressure

400

If a solution has a pOH = 9.8, what is the [H3O+] of the solution?

6.31 x 10-5M

400

Are lead-acid batteries rechargeable?

Yes -- they are secondary batteries.

500

What types of equations do you need the van't Hoff factor for?

What is the van't Hoff factor for the following molecule? NaNO3

Colligative properties (osmotic pressure, freezing point depression, boiling point, vapor pressure)

2 (Na and NO3)

500

What is the fundamental difference between Q and K of a reaction?

Q can be calculated at any time during the reaction, while K can only be calculated at equilibrium. 

500

During a weak-acid/strong-base titration, how do you treat the titration before the equivalence point?

You treat it like a buffer system! Henderson-Hasselbalch :)

500

In the reaction below, which is the oxidizing agent?

ClO3- + I2 --> Cl- + IO3-

ClO3- is the oxidizing agent because it is being reduced.
