Consider two organic molecules, ethanol and benzene. One dissolves in water and the other does not. Why?

Ethanol contains a polar O-H Bond, and benzene does not. Ethanol C2H6O and Benzene C6H6

Which of the following is paired incorrectly?
A. H2SO4 - strong acid
B. HNO3 - weak acid
C. Ba(OH)2 - strong acid
D. HCl - strong acid
E. NH3 - weak acid

B. HNO3 - weak acid. HNO3 is a strong acid.

You have equal masses of different solutes dissolved in equal volumes of solution. Which of the solutes would make the solution having the highest molar concentration?
A. NaOH
B. KCl
C. KOH
D. LiOH
E. All the same

D. LiOH When the volume of the solution and mass of the compounds taken are the same, the lower MM compound would have highest molar concentration.

Which of the following do you need to know to be able to calculate the molarity of a salt solution?
I. the mass of salt added
II. the molar mass of the salt
III. the volume of water added
IV. the total volume of the solution

A. I, III
B. I, II, III
C. II, III
D. I, II, IV
E. You need all of the information

D. I, II, IV - The mass of the salt added, The molar mass of the salt, the total volume of the solution

The following reactions:
*Pb2+ + 2l- -> PbI2
*2Ce4+ + 2I - > I2 + 2Ce3+
*HOAc + NH3 - >NH4+ + OAc- are examples of?

A. acid-base reactions
B. unbalanced reactions
C. precipitation, acid-base, and redox reactions, respectively
D. Redox, acid-base, and precipitation reactions, respectively
E. Precipitation, redox, and acid-base reactions, respectively

E. precipitation, redox, and acid-base reactions, respectively

Aqueous solutions of sodium sulfide and copper (II) chloride are mixed together. Which statement is correct?

A. Both NaCl and CuS precipitate from solution
B. No reaction will occur.
C. CuS will precipitate from solution.
D. NaCl will precipitate from solution
E. A gas is released

C. CuS will precipitate from solution - copper is insoluble.

Insoluble Sulfate salts?

BaSO4, PbSO4, Hg2SO4 and CaSO4
Barium/Lead/Mercury/Calcium Sulfate Salts

When solutions of strontium chloride and sodium carbonate react, which of the following is a spectator ion?

A. Strontium Ion
B. Chloride Ion
C. Sodium Ion
D. Carbonate Ion
E. Two of these

E. Two of these

You have separate solutions of HCl and H2SO4 with the same concentrations in terms of molarity. You wish to neutralize a solution of NaOH. Which acid solution would require more volume (in mL) to neutralize the base?
A. The HCl solution
B. The H2SO4 solution
C. You need to know the acid concentrations to answer this question.
D.

A. The HCl Solution - HCl is monoprotic acid (one H+ ion) and H2SO4 is diprotic acid (two H+ ions). When taken in equal concentrations, it would require double the volume of HCl than that of H2SO4.
