This calculator helps you determine the stoichiometric relationships in the reaction between ammonia (NH3) and 92% nitric oxide (NO) to produce water (H2O). Learn how to balance the chemical equation and calculate the required quantities for complete reactions.
Balanced Chemical Equation
The reaction between ammonia and nitric oxide produces water and nitrogen gas. The balanced chemical equation is:
This equation shows that 4 moles of ammonia react with 5 moles of nitric oxide to produce 4 moles of nitrogen gas and 6 moles of water. The equation is balanced with equal numbers of atoms for each element on both sides of the reaction.
Stoichiometry Calculation
Stoichiometry allows us to determine the quantitative relationships between reactants and products in chemical reactions. For the reaction NH3 + 92% NO → H2O, we can calculate:
- The amount of water produced from given amounts of ammonia and nitric oxide
- The limiting reactant when different quantities are used
- The theoretical yield of water based on reactant amounts
The key stoichiometric relationships are based on the balanced equation coefficients:
This means the ratio of ammonia to nitric oxide to water is 4:5:6 by moles.
Worked Example
Let's calculate how much water is produced when 8 moles of ammonia react with 10 moles of 92% nitric oxide.
- First, account for the 92% purity of nitric oxide:
10 moles NO × 0.92 = 9.2 moles pure NO
- Determine the limiting reactant by comparing with the stoichiometric ratio:
For 8 moles NH3, needed NO = 8 × (5/4) = 10 moles
Since we have 9.2 moles of NO (which is more than needed), ammonia is the limiting reactant.
- Calculate water produced from limiting reactant:
8 moles NH3 × (6/4) = 12 moles H2O
Therefore, 12 moles of water are produced from 8 moles of ammonia and 10 moles of 92% nitric oxide.
Practical Applications
Understanding this reaction is important in several industrial and environmental contexts:
- Water production in chemical manufacturing processes
- Nitrogen recovery systems in industrial settings
- Environmental monitoring of ammonia and nitric oxide levels
- Process optimization in chemical engineering
Note: The 92% purity of nitric oxide is an assumption. Actual purity may vary based on production methods and quality control standards.
FAQ
- What is the balanced equation for NH3 + NO → H2O?
- The balanced equation is 4 NH3 + 5 NO → 4 N2 + 6 H2O.
- How do I calculate the amount of water produced?
- Multiply the moles of limiting reactant by the stoichiometric ratio (6 moles H2O per 4 moles NH3).
- What is the limiting reactant in this reaction?
- The reactant that produces less product based on the stoichiometric ratio is the limiting reactant.
- Why is nitric oxide considered 92% pure in this calculation?
- Industrial-grade nitric oxide typically contains impurities, and 92% is a common assumed purity level.
- How does temperature affect this reaction?
- Temperature affects reaction rates but not the stoichiometric ratios in this idealized calculation.
