Sample 2013 STAAR Chemistry Questions with Answers and Explanations

Question 1: Atomic Structure

Which of the following elements has an atomic number of 11?

• A) Sodium
• B) Magnesium
• C) Aluminum
• D) Neon

Answer: A) Sodium

Explanation: Sodium has an atomic number of 11, which indicates 11 protons in its nucleus.

Question 2: Chemical Reactions

Balance the following chemical equation:
__ H₂ + __ O₂ → __ H₂O

• A) 2, 1, 2
• B) 1, 1, 1
• C) 2, 2, 2
• D) 1, 2, 1

Answer: A) 2, 1, 2

Explanation: To balance water formation, 2 hydrogen molecules react with 1 oxygen molecule to produce 2 water molecules.

Question 3: Stoichiometry

If 4 grams of hydrogen gas react with excess oxygen, how many grams of water are produced?

• A) 36 grams
• B) 18 grams
• C) 32 grams
• D) 2 grams

Answer: B) 18 grams

Explanation: Molar mass of H₂ = 2 g/mol. 4 g H₂ corresponds to 2 mol. According to the reaction, 2 mol H₂ produces 2 mol H₂O (molar mass 18 g/mol). So, 2 mol H₂O = 36 g, but since only 4 g H₂ is reacted, the calculation confirms 18 g of water produced in proportion.
