Sample Practice Questions for Holt Chemistry Chapter 10
Engaging with practice questions is essential for mastering Chapter 10 concepts. Below are examples that mirror typical Holt Chemistry practice test questions:
Question 1: Balancing Chemical Equations
Balance the following chemical equation:
\[ \text{C}_2\text{H}_6 + \text{O}_2 \rightarrow \text{CO}_2 + \text{H}_2\text{O} \]
Answer:
Balanced equation:
\[ 2 \text{C}_2\text{H}_6 + 7 \text{O}_2 \rightarrow 4 \text{CO}_2 + 6 \text{H}_2\text{O} \]
Question 2: Mole Conversions
Calculate the number of moles in 18 grams of water (H₂O).
Solution:
- Molar mass of H₂O = 18.02 g/mol
- Moles = mass / molar mass = 18 g / 18.02 g/mol ≈ 1 mol
Question 3: Stoichiometry
If 2 moles of methane (CH₄) react with excess oxygen, how many moles of carbon dioxide (CO₂) are produced?
Answer:
From the balanced equation:
\[ \text{CH}_4 + 2 \text{O}_2 \rightarrow \text{CO}_2 + 2 \text{H}_2\text{O} \]
1 mol CH₄ produces 1 mol CO₂, so 2 mol CH₄ produce 2 mol CO₂.
Question 4: Limiting Reactant
Given 5 grams of hydrogen gas (H₂) and 20 grams of nitrogen gas (N₂), determine the limiting reactant in the formation of ammonia (NH₃). The reaction:
\[ \text{N}_2 + 3 \text{H}_2 \rightarrow 2 \text{NH}_3 \]
Solution:
- Molar mass of H₂ = 2.02 g/mol
- Molar mass of N₂ = 28.02 g/mol
Calculate moles:
- H₂: 5 g / 2.02 g/mol ≈ 2.48 mol
- N₂: 20 g / 28.02 g/mol ≈ 0.71 mol
From the reaction:
- 1 mol N₂ reacts with 3 mol H₂
- For 0.71 mol N₂, required H₂ = 0.71 × 3 ≈ 2.13 mol
Since available H₂ is 2.48 mol, which is more than required, N₂ is the limiting reactant.
