Mole ratios are conversion factors derived from the coefficients of a balanced chemical equation. These ratios are crucial for stoichiometric calculations, allowing us to convert between moles of reactants and products.
Consider the balanced chemical equation: 2H₂ + O₂ → 2H₂O
1. The coefficient for H₂ is .
2. The coefficient for O₂ is .
3. The coefficient for H₂O is .
4. For the reaction N₂ + 3H₂ → 2NH₃, what is the mole ratio of H₂ to NH₃?
1:2
3:2
2:3
1:3
5. In the combustion of methane CH₄ + 2O₂ → CO₂ + 2H₂O, what is the mole ratio of CH₄ to O₂?
1:1
1:2
2:1
2:2
For the reaction: 2Al + 3Cl₂ → 2AlCl₃
6. If you have 4 moles of Al, how many moles of AlCl₃ can be produced?
7. If you want to produce 6 moles of AlCl₃, how many moles of Cl₂ are required?
8. Mole ratios can only be used to compare reactants to products, not reactants to reactants.
True
False
9. A balanced chemical equation is essential for determining correct mole ratios.
True
False
Match the chemical reaction with the correct mole ratio of the specified substances.
10. 2Na + Cl₂ → 2NaCl (Na to Cl₂)
a. 2:1
11. C₃H₈ + 5O₂ → 3CO₂ + 4H₂O (O₂ to H₂O)
b. 5:4
12. Fe₂O₃ + 3CO → 2Fe + 3CO₂ (Fe₂O₃ to Fe)
c. 1:2
