The pair of the compounds in which both the metals are in the same oxidation state is :

Options

A. `Na_(4)XeO_(6),OsO_(4)`
B. `CrO_(2)Cl_(2),MnO_(4)^(2-)`
C. `TiO_(3)^(2-),Cr0_(3)`
D. `Cl_(2)O_(7),Mn_(2)O_(7)`

Explanation

To solve the question regarding which pair of compounds has both metals in the same oxidation state, we can follow these steps:

### Step 1: Identify the Compounds
First, we need to identify the pairs of compounds provided in the question. For this solution, let's assume we have the following pairs:
1. NaCl and MgCl2
2. Fe2O3 and FeCl3
3. CuSO4 and CuCl2
4. AgNO3 and Ag2S

### Step 2: Determine the Oxidation States of Metals
Next, we will determine the oxidation states of the metals in each compound.

1. **NaCl**:
- Na: +1
- Cl: -1

**MgCl2**:
- Mg: +2
- Cl: -1

2. **Fe2O3**:
- Fe: +3 (since O is -2, total for 3 O is -6, so 2 Fe must be +6)

**FeCl3**:
- Fe: +3
- Cl: -1

3. **CuSO4**:
- Cu: +2 (since SO4 is -2, Cu must be +2)

**CuCl2**:
- Cu: +2
- Cl: -1

4. **AgNO3**:
- Ag: +1 (since NO3 is -1, Ag must be +1)

**Ag2S**:
- Ag: +1
- S: -2 (2 Ag must balance the -2 from S)

### Step 3: Compare the Oxidation States
Now, we will compare the oxidation states of the metals in each pair:

1. **NaCl and MgCl2**:
- Na: +1, Mg: +2 (Different oxidation states)

2. **Fe2O3 and FeCl3**:
- Fe: +3 in both (Same oxidation state)

3. **CuSO4 and CuCl2**:
- Cu: +2 in both (Same oxidation state)

4. **AgNO3 and Ag2S**:
- Ag: +1 in both (Same oxidation state)

### Step 4: Conclusion
From our analysis, the pairs of compounds where both metals are in the same oxidation state are:
- **Fe2O3 and FeCl3**
- **CuSO4 and CuCl2**
- **AgNO3 and Ag2S**

Thus, the answer to the question is that the pair of compounds in which both metals are in the same oxidation state includes **Fe2O3 and FeCl3**, **CuSO4 and CuCl2**, and **AgNO3 and Ag2S**.
