Sample Questions and Answers

Here are some sample FRQs from past exams:

Section I

A 1.00 g sample of an unknown metal is reacted with excess hydrochloric acid. The reaction produces 0.250 L of hydrogen gas at a temperature of 25°C and a pressure of 1.00 atm. What is the molar mass of the unknown metal?

Answer: 56.0 g/mol

Section II

1. What is the pH of a 0.10 M solution of acetic acid (CH3COOH)?
2. A solution of sodium chloride (NaCl) has a concentration of 0.50 M. What is the molarity of the chloride ions in the solution?

Answers:

1. 2.87
2. 0.50 M

Section III

Which of the following reactions is spontaneous?

A. N2(g) + 3H2(g) → 2NH3(g)
B. Cu(s) + 2Ag+(aq) → Cu2+(aq) + 2Ag(s)
C. 2H2O(l) → 2H2(g) + O2(g)
D. CO2(g) + H2O(l) → H2CO3(aq)

Answer: B. Cu(s) + 2Ag+(aq) → Cu2+(aq) + 2Ag(s)

Tips and Tricks

Here are some tips and tricks for answering the FRQs:

• Practice, practice, practice! The best way to prepare for the FRQs is to practice answering them. There are many resources available online and in your textbook.
