A fire extinguisher contains `H_(2)SO_(4)` and

Options

A. `NaHCO_(3)` and `Na_(2)CO_(3)`
B. `NaHCO_(3)` solution
C. `Na_(2)CO_(3)`
D. `CaCO_(3)`

Explanation

To solve the question regarding the contents of a fire extinguisher that contains `H₂SO₄`, we will go through the following steps:

### Step-by-Step Solution:

1. **Identify the Components**: The question states that the fire extinguisher contains `H₂SO₄` (sulfuric acid). We need to determine what else it contains to produce carbon dioxide (CO₂) for extinguishing fires.

**Hint**: Think about common substances that react with sulfuric acid to produce gases.

2. **Consider Common Fire Extinguisher Reactions**: Fire extinguishers often use a reaction that produces CO₂. A well-known reaction involves sodium bicarbonate (baking soda), which is `NaHCO₃`.

**Hint**: Recall that sodium bicarbonate is often used in fire extinguishers because it can release CO₂ when it reacts with acids.

3. **Write the Chemical Reaction**: The reaction between sodium bicarbonate and sulfuric acid can be written as:
\[ 2 \text{NaHCO}_3 + \text{H}_2\text{SO}_4 \rightarrow \text{Na}_2\text{SO}_4 + 2 \text{H}_2\text{O} + 2 \text{CO}_2 \]
This shows that when sodium bicarbonate reacts with sulfuric acid, it produces sodium sulfate, water, and carbon dioxide.

**Hint**: Look for the products of the reaction to understand how CO₂ is generated.

4. **Conclusion**: Based on the reaction, we can conclude that the fire extinguisher contains both `H₂SO₄` and `NaHCO₃` (sodium bicarbonate). This combination allows for the production of CO₂, which is effective in extinguishing fires.

**Hint**: Think about the purpose of the fire extinguisher and how the components work together to achieve that.

### Final Answer:
The fire extinguisher contains `H₂SO₄` and `NaHCO₃` (sodium bicarbonate).
