B. If product is oxy acid with -ous suffix
C. If product are two oxy acids one with -ic suffix and otherone with -ous suffix.
D. If product is not oxy acid, neither with -ic suffix nor with -ous suffix

Answer

To solve the reaction \( H_4P_2O_6 + H_2O \rightarrow H_3PO_3 + H_3PO_4 \), we will analyze the reactants and products step by step.

### Step 1: Identify the Reactants and Products
- **Reactants:**
- \( H_4P_2O_6 \) (Diphosphoric acid)
- \( H_2O \) (Water)

- **Products:**
- \( H_3PO_3 \) (Phosphorous acid)
- \( H_3PO_4 \) (Phosphoric acid)

### Step 2: Determine the Type of Reaction
This reaction involves the conversion of a diphosphoric acid and water into two different oxyacids. The reaction can be classified as a **hydrolysis reaction**, where water is used to break down a compound into simpler products.

### Step 3: Analyze the Products
- **Product 1:** \( H_3PO_3 \) (Phosphorous acid)
- Contains hydrogen (H), oxygen (O), and phosphorus (P).
- It has the structure with one P atom, three O atoms, and three H atoms.

- **Product 2:** \( H_3PO_4 \) (Phosphoric acid)
- Contains hydrogen (H), oxygen (O), and phosphorus (P).
- It has the structure with one P atom, four O atoms, and three H atoms.

### Step 4: Check for Oxyacid Characteristics
To be classified as an oxyacid:
1. It must contain hydrogen atoms, oxygen atoms, and at least one other element (in this case, phosphorus).
2. At least one hydrogen atom must be bonded to an oxygen atom, which can dissociate to form \( H^+ \) ions.

Both products meet these criteria:
- \( H_3PO_3 \) has the formula indicating it can dissociate to release \( H^+ \).
- \( H_3PO_4 \) also has the formula indicating it can dissociate to release \( H^+ \).

### Step 5: Identify the Suffixes
- \( H_3PO_3 \) is known as phosphorous acid (with the suffix "ous").
- \( H_3PO_4 \) is known as phosphoric acid (with the suffix "ic").

### Conclusion
Since we have two products which are both oxyacids, one with the "ous" suffix and the other with the "ic" suffix, the correct answer is:

**Option C: The products are two oxyacids, one with "ous" suffix and the other with "ic" suffix.**
