#### Problem Statement:
1. Write the balanced chemical equation for the reaction. Physical states are optional.
    
    **Chemical Equation:**
    [Input Box for Equation]
    
2. What is the limiting reactant?
    - [ ] Calcium hydroxide
    - [ ] Hydrochloric acid

3. How many grams of salt are formed after the reaction is complete?

    **Mass of salt:**
    [Input Box]

4. How many grams of the excess reactant remain after the reaction is complete?

    **Remaining mass of excess reactant:**
    [Input Box]

### Explanation of Graphs or Diagrams:

This document does not contain any graphs or diagrams.

### Notes:
- Ensure the chemical equation is balanced in terms of both mass and charge.
- Identify the limiting reactant by comparing the molar amounts of reactants based on stoichiometry.
- Calculate the mass of the resultant salt using the stoichiometrically equivalent amount of the limiting reactant.
- Determine the remaining mass of the excess reactant by subtracting the amount used in the reaction from the initial amount.

This interactive problem helps to understand stoichiometry and limiting reactant concepts in chemical reactions.

**Explanation:**
After a chemical reaction, it is crucial to determine the amount of excess reactant that remains. This residual quantity gives insight into the efficiency and completeness of the reaction. By calculating the mass of salt produced, we can further determine how many grams of the excess reactant are still present.

To assist in these calculations, follow these steps:

1. **Identify the limiting reactant:** This reactant is entirely consumed during the reaction.
2. **Calculate the theoretical yield:** This is the maximum amount of product (e.g., salt) that can be formed.
3. **Determine the actual yield:** This is the quantity obtained from the experiment.
4. **Compute the excess reactant remaining:** Subtract the amount consumed by the reaction from the initial amount to find the leftover.

A clear understanding of these concepts will aid in better managing reactants and optimizing the reaction conditions for future experiments.
