Answer

To solve the reaction \( \text{ClF}_3 + \text{H}_2\text{O} \rightarrow \text{HClO}_2 + \text{HF} \), we need to analyze the products formed and determine the nature of these products.

### Step-by-Step Solution:

1. **Identify the Reactants and Products**:
- Reactants: \( \text{ClF}_3 \) (Chlorine trifluoride) and \( \text{H}_2\text{O} \) (Water).
- Products: \( \text{HClO}_2 \) (Chlorous acid) and \( \text{HF} \) (Hydrofluoric acid).

2. **Determine the Type of Products**:
- **Oxyacid**: An oxyacid is an acid that contains hydrogen, oxygen, and another element. In our case, \( \text{HClO}_2 \) contains hydrogen, oxygen, and chlorine, making it an oxyacid.
- **Non-Oxyacid**: \( \text{HF} \) contains hydrogen and fluorine but no oxygen, so it is not classified as an oxyacid.

3. **Analyze the Oxyacid**:
- The structure of \( \text{HClO}_2 \) can be represented as \( \text{Cl} \) bonded to two \( \text{O} \) atoms and one \( \text{H} \) atom. When it dissociates, it releases a proton (H⁺) and forms the chlorite ion \( \text{ClO}_2^- \).
- The naming convention for oxyacids states that if the corresponding oxyanion ends with "ite," the acid name will end with "ous." Therefore, \( \text{HClO}_2 \) is named chlorous acid.

4. **Identify the Naming Convention**:
- Since \( \text{HClO}_2 \) is an oxyacid with the suffix "ous," we can conclude that our product is an oxyacid with the "ous" suffix.
- The other product, \( \text{HF} \), does not fit the criteria of an oxyacid.

5. **Conclusion**:
- In the given reaction, we have one oxyacid (chlorous acid) with the "ous" suffix and one non-oxyacid (HF). Therefore, the correct option is that the product is an oxyacid with the "ous" suffix.

### Final Answer:
The correct option is that the product is an oxyacid with the "ous" suffix.
