Sample Chemistry Practice Questions with Answers in PDF Format
To illustrate the type of questions you may encounter, here are sample problems with solutions:
Question 1: Atomic Structure
What is the number of neutrons in an isotope of carbon-14?
Answer:
Carbon-14 has an atomic number of 6 (number of protons).
Mass number = 14 (protons + neutrons).
Number of neutrons = 14 - 6 = 8.
Question 2: Chemical Bonding
Describe the type of bond formed between sodium and chlorine in sodium chloride.
Answer:
Sodium (Na) donates an electron to chlorine (Cl), forming an ionic bond. The result is Na⁺ and Cl⁻ ions held together by electrostatic attraction, creating an ionic bond.
Question 3: Stoichiometry
How many grams of water are produced when 4 grams of hydrogen gas react with excess oxygen?
Answer:
Reaction: 2H₂ + O₂ → 2H₂O
Molar mass of H₂ = 2 g/mol
Number of moles of H₂ = 4 g / 2 g/mol = 2 mol
According to the balanced equation, 2 mol H₂ produce 2 mol H₂O.
Molar mass of H₂O = 18 g/mol
Mass of water produced = 2 mol × 18 g/mol = 36 g.
