AgCl on fusion with sodium carbonate, gives :

Options

A. `Ag_2CO_3`
B. `Ag_2O`
C. Ag
D. `Ag_2C_2`

Answer

To solve the question "AgCl on fusion with sodium carbonate gives:", we will follow these steps:

### Step 1: Write the Chemical Reaction
When silver chloride (AgCl) is fused with sodium carbonate (Na2CO3), a chemical reaction occurs. The reaction can be represented as:
\[ 4 \text{AgCl} + 2 \text{Na}_2\text{CO}_3 \rightarrow 4 \text{Ag} + 2 \text{CO}_2 + 4 \text{NaCl} + \text{O}_2 \]

### Step 2: Identify the Products
From the balanced equation, we can identify the products formed during the reaction:
- Silver (Ag)
- Carbon dioxide (CO2)
- Sodium chloride (NaCl)
- Oxygen (O2)

### Step 3: Analyze the Options
Now, we need to match the products with the options provided in the question. The main products of the reaction are silver (Ag), sodium chloride (NaCl), carbon dioxide (CO2), and oxygen (O2).

### Step 4: Determine the Correct Option
Among the products, silver (Ag) is a notable product that is often highlighted in such questions. Therefore, the correct answer to the question is:
- **Silver (Ag)**

### Final Answer
The answer is **Ag** (Option C).
