Which of the following is a/are strong acids `HNO_(3),HCl,CH_(3)COOH,H_(2)CO_(3)`

Options

A. `HNO_(3),H_(2)CO_(3)`
B. `HNO_(3),HCl`
C. `HCl,CH_(3)COOH`
D. `H_(2)CO_(3),CH_(3)COOH`

Explanation

To determine which of the following compounds are strong acids, we will analyze each one based on their ability to dissociate and release hydrogen ions (H⁺) in solution.

### Step-by-Step Solution:

1. **Identify the Compounds:**
The compounds given are:
- HNO₃ (Nitric acid)
- HCl (Hydrochloric acid)
- CH₃COOH (Acetic acid)
- H₂CO₃ (Carbonic acid)

2. **Define Strong Acids:**
Strong acids are substances that completely dissociate in water, releasing H⁺ ions readily. Examples of strong acids include HCl, HNO₃, H₂SO₄, and HClO₄.

3. **Analyze Each Compound:**
- **HNO₃ (Nitric Acid):** This is a strong acid as it completely dissociates in solution to release H⁺ ions.
- **HCl (Hydrochloric Acid):** This is also a strong acid, known for its complete dissociation in water.
- **CH₃COOH (Acetic Acid):** This is a weak acid because it does not completely dissociate in solution; it only partially releases H⁺ ions.
- **H₂CO₃ (Carbonic Acid):** This is also a weak acid as it does not fully dissociate in solution.

4. **Conclusion:**
From the analysis, the strong acids among the given options are:
- HNO₃
- HCl

### Final Answer:
The strong acids from the given list are HNO₃ and HCl.
