Takings Clause
Privileges and Immunities Clause
Supremacy Clause
Elastic Clause (Correct answer)

Correct answer: Elastic Clause

The Necessary and Proper Clause is nicknamed the Elastic Clause for its flexibility.

Question 16: Faraday's constant (about 96,485 C/mol) represents the charge of:

One mole of electrons (Correct answer)
One electron
One mole of protons and electrons
One proton

Correct answer: One mole of electrons

Faraday's constant is the total charge carried by one mole of electrons.

Question 17: In an electrolytic cell, the source of energy driving the nonspontaneous reaction is:

An external power supply (Correct answer)
A salt bridge
Heat from the surroundings
Spontaneous oxidation

Correct answer: An external power supply

Electrolytic cells require an external power source to drive nonspontaneous reactions.

Question 18: In the electrolysis of aqueous NaCl (brine), why is hydrogen often produced instead of sodium at the cathode?

Water is more easily reduced than Na⁺ (Correct answer)
Sodium is denser than water
Cl⁻ blocks the cathode
Na⁺ cannot reach the cathode

Correct answer: Water is more easily reduced than Na⁺

Water has a more favorable reduction potential than Na⁺, so H₂ is produced preferentially.

Question 19: How does the sign of the anode differ between galvanic and electrolytic cells?

Negative in galvanic, positive in electrolytic (Correct answer)
Positive in both
Positive in galvanic, negative in electrolytic
Negative in both

Correct answer: Negative in galvanic, positive in electrolytic

The anode is negative in a galvanic cell but positive in an electrolytic cell.

Question 20: If 2.0 mol of electrons pass through a cell depositing a +2 metal, how many moles of metal are deposited?

1.0 mol (Correct answer)
2.0 mol
0.5 mol
4.0 mol

Correct answer: 1.0 mol

Each metal ion requires 2 electrons, so 2.0 mol electrons deposit 1.0 mol of metal.

Question 21: As temperature increases, the value of Kw for water:

Becomes zero
Stays constant
Decreases
Increases (Correct answer)

Correct answer: Increases

Water's self-ionization is endothermic, so Kw increases with temperature.

Question 22: Which oxide, when dissolved in water, produces an acidic solution?

SO3 (Correct answer)
CaO
K2O
Na2O

Correct answer: SO3

SO3 reacts with water to form sulfuric acid, giving an acidic solution.

Question 23: A buffer solution is typically made from:

A strong acid and a strong base
A weak acid and its conjugate base (Correct answer)
Pure water and salt
Two strong acids

Correct answer: A weak acid and its conjugate base

Buffers consist of a weak acid and its conjugate base (or weak base and conjugate acid).

Question 24: Adding a small amount of strong acid to a buffer causes the buffer to:

Become a strong acid
Increase pH sharply
Resist large pH change (Correct answer)
Decrease pH sharply

Correct answer: Resist large pH change

The conjugate base neutralizes added acid, so the pH changes only slightly.

Question 25: The percent ionization of a weak acid increases as the solution becomes:

More concentrated
More dilute (Correct answer)
Hotter only
More acidic

Correct answer: More dilute

Dilution shifts the dissociation equilibrium toward more ionization.
