Answer

To solve the question regarding the reaction of silicon tetrachloride (SiCl₄) with water (H₂O) to form silicic acid (H₄SiO₄) and hydrochloric acid (HCl), we will analyze the products formed and classify them accordingly.

### Step-by-Step Solution:

1. **Identify the Reactants and Products:**
- The reactants are SiCl₄ (silicon tetrachloride) and H₂O (water).
- The products formed are H₄SiO₄ (silicic acid) and HCl (hydrochloric acid).

2. **Determine the Type of Reaction:**
- This reaction is a hydrolysis reaction where SiCl₄ reacts with water to form an acid and hydrochloric acid.

3. **Analyze the Product H₄SiO₄:**
- H₄SiO₄ contains hydrogen (H), oxygen (O), and silicon (Si).
- Since it contains hydrogen and oxygen, along with another element (Si), it qualifies as an oxyacid.

4. **Classify the Oxyacid:**
- The anion derived from H₄SiO₄ is H₃SiO₄⁻. The naming convention for oxyacids states that if the anion ends in "-ate," the acid name will end in "-ic."
- Since H₄SiO₄ is derived from the anion H₃SiO₄⁻, it is called silicic acid, which ends in "-ic."

5. **Analyze the Product HCl:**
- HCl (hydrochloric acid) does not contain oxygen; it consists of hydrogen and chlorine.
- Therefore, HCl is not classified as an oxyacid.

6. **Conclusion:**
- In this reaction, we have one oxyacid (H₄SiO₄) with the "-ic" suffix and one non-oxyacid (HCl).
- The correct classification for the product H₄SiO₄ is that it is an oxyacid with the "-ic" suffix.

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