Question
**Reaction Analysis** Consider the reaction involving the following solutions: - **Solution 1**: 20.0 mL of 0.220 M C₅H₅NHCl (Pyridinium chloride) - **Acid Dissociation Constant (Ka)**: 5.9 x 10⁻⁶ - **Solution 2**: 12.0 mL of 0.241 M CsOH (Cesium hydroxide) This reaction involves mixing a weak acid (pyridinium chloride) with a strong base (cesium hydroxide). The goal of this analysis is to understand the chemical interaction and potential outcomes, such as pH changes, precipitation, or buffer formations. The dissociation constant (Ka) provides insight into the strength of the weak acid and its propensity to donate protons in solution.

**Question**: How many moles of C₅H₅N are produced after the reaction goes to completion? This question asks about the quantity of pyridine (C₅H₅N) formed when a given chemical reaction finishes completely. Understanding this topic requires knowledge of stoichiometry, which is the calculation of reactants and products in chemical reactions. Typically, this involves using balanced chemical equations to determine the proportions of substances involved. For further guidance: - Review the balanced equation for the reaction, identifying reactants and products. - Use the stoichiometric coefficients from the balanced equation to determine the mole ratio between reactants and C₅H₅N. - Calculate the moles of C₅H₅N formed using the initial quantities of the reactants and the mole ratios from the equation. Make sure to apply these steps to solve the problem accurately.
