Question
![### Chemical Reactions and Limiting Reagents
In this example, we consider a reaction between potassium hydroxide and phosphoric acid.
**Reaction:**
\[ \text{potassium hydroxide} (\text{aq}) + \text{phosphoric acid} (\text{aq}) \rightarrow \text{potassium phosphate} (\text{aq}) + \text{water} (\text{l}) \]
#### Given Data:
- **65.3 grams** of potassium hydroxide (\( KOH \)) are allowed to react with **41.8 grams** of phosphoric acid (\( H_3PO_4 \)).
##### Questions to Calculate:
1. What is the maximum amount of potassium phosphate (\( K_3PO_4 \)) that can be formed?
- Answer: **______** grams
2. What is the **formula** for the limiting reagent?
- Answer: **______**
3. What amount of the excess reagent remains after the reaction is complete?
- Answer: **______** grams
To solve these questions, students should use stoichiometry to identify the limiting reagent, determine the maximum yield of potassium phosphate, and calculate the leftover quantity of the excess reagent. The balanced chemical equation and molar masses of the reactants and products will be crucial for these calculations.
**Note**: This is a theoretical exercise typically found in chemistry curricula, designed to reinforce understanding of chemical reactions, stoichiometry, and limiting reagents.
For detailed guidance on solving, refer to stoichiometry chapters in chemical textbooks or online educational resources.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Febc6c9e4-20c2-4aa0-9f79-b773de998cf1%2Fea51c8c7-9895-43f6-8aef-b166c6054002%2Flj0d88g_processed.png&w=3840&q=75)
