**Category:** Inorganic Chemistry  
**Subtype:** Chemical Reactions, Stoichiometry  

**Problem Overview:**  
This problem involves two solutions:  
- Solution X contains 1 M potassium bicarbonate (\(\mathrm{KHCO}_{3}\)) and 1 M sodium carbonate (\(\mathrm{Na}_{2}\mathrm{CO}_{3}\)).  
- Solution Y contains 1 M sulfuric acid (\(\mathrm{H}_{2}\mathrm{SO}_{4}\)) and 1 M hydrochloric acid (HCl).  

The task is to determine the volume of carbon dioxide gas (\(\mathrm{CO}_{2}\)) produced when 100 mL of solution Y is added to 200 mL of solution X, and the mass of the precipitate formed when excess barium hydroxide (\(\mathrm{Ba(OH)_{2}}\)) is added to the resulting solution E.  

**Key Points to Solve:**  
- Calculate the amount of \(\mathrm{CO}_{2}\) produced from the reaction between the acids in solution Y and the bicarbonate and carbonate in solution X.  
- Determine the mass of the precipitate formed when barium hydroxide reacts with the remaining components in solution E.  

**Final Values to Find:**  
- Mass of the precipitate (m) in grams.  
- Volume of \(\mathrm{CO}_{2}\) gas (V) produced in liters.  

**Answer Choices:**  
A. 82.4 g and 1.12 L  
B. 82.4 g and 2.24 L  
C. 59.1 g and 1.12 L  
D. 59.1 g and 2.24 L
