Question
**Learning Goal:** To understand how to use stoichiometry to convert between quantities of reactants and products in chemical equations. **Stoichiometry** describes the quantitative relationships among the reactants and products of a balanced reaction by directly comparing mole ratios. Stoichiometry can be used to convert mass, number of moles, or number of particles between products and reactants, as shown in the flowchart displayed in the figure. **Flowchart Explanation:** Substance A: - Start with the number of particles. - Use Avogadro's number to convert to moles. - Convert moles to mass using molar mass. - Once you have moles, use coefficients from balanced chemical equations to find moles of Substance B. Substance B: - From moles, convert to number of particles using Avogadro's number. - Convert moles to mass using molar mass. **Converting between Quantities:** To convert from a given quantity of one reactant or product to the quantity of another reactant or product: 1. First, convert the given quantity to moles. Use molar masses to convert masses to moles, and use Avogadro's number (6.02 x 10²³ particles per mole) to convert the number of particles to moles. 2. Next, convert moles of the given reactant or product to moles of the desired reactant or product using the coefficients of the balanced chemical equation. For example, in the chemical equation: \(2\text{H}_2 + \text{O}_2 \rightarrow 2\text{H}_2\text{O}\) The coefficients tell us that 2 mol of \( \text{H}_2 \) reacts with 1 mol of \( \text{O}_2 \) to produce 2 mol of \( \text{H}_2\text{O} \). 3. Finally, convert moles of the desired reactant or product back to the desired units. Again, use molar masses to convert from moles to masses, and use Avogadro's number to convert from moles to the number of particles. **Reaction of Hydrogen and Nitrogen to form Ammonia:** Hydrogen gas, \( \text{H}_2 \), reacts with nitrogen gas, \( \text{N}_2 \), to form ammonia gas, \( \text{NH}_
