Read each question carefully and provide your answers in the space provided. Show all your work for calculations.

1. A mole ratio is a conversion factor that relates the amounts in moles of any two substances involved in a  .

2. Mole ratios are derived from the   in a balanced chemical equation.

3. In the reaction 2H₂ + O₂ → 2H₂O, the mole ratio of H₂ to O₂ is  .

Consider the balanced chemical equation: N₂(g) + 3H₂(g) → 2NH₃(g)

4. How many moles of NH₃ can be produced from 4.5 moles of H₂?

5. If 2.0 moles of N₂ react completely, how many moles of H₂ are consumed?

6. For the reaction 2Na + Cl₂ → 2NaCl, what is the mole ratio of Na to NaCl?

7. Mole ratios can only be determined from unbalanced chemical equations.

8. The coefficients in a balanced chemical equation represent both the number of moles and the number of particles.

9. Consider the reaction: CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(g). If 32 grams of O₂ react, how many moles of CO₂ are produced? (Molar mass of O₂ = 32.00 g/mol)
