Options

A. `KAg(CN)_(2)`
B. `K_(2)Ag (CN)_(2)`
C. `K_(2)Ag (CN)_(4)`
D. `KAg (CN)_(4)`

Explanation

To solve the question regarding the reaction of Argentite with potassium cyanide, we can follow these steps:

### Step 1: Identify the formula of Argentite
Argentite is a mineral that contains silver in the form of silver sulfide. The chemical formula for Argentite is:
\[ \text{Ag}_2\text{S} \]

### Step 2: Write the formula for potassium cyanide
Potassium cyanide is represented by the formula:
\[ \text{KCN} \]

### Step 3: Set up the reaction
When Argentite (\( \text{Ag}_2\text{S} \)) reacts with potassium cyanide (\( \text{KCN} \)), it forms a complex compound. The reaction can be represented as follows:
\[ \text{Ag}_2\text{S} + \text{KCN} \rightarrow \text{KAg(CN)}_2 + \text{K}_2\text{S} \]

### Step 4: Balance the reaction
To balance the reaction, we need to ensure that the number of atoms of each element is the same on both sides. The balanced equation is:
\[ \text{Ag}_2\text{S} + 4 \text{KCN} \rightarrow 2 \text{KAg(CN)}_2 + \text{K}_2\text{S} \]

### Step 5: Identify the product
From the balanced equation, we can see that the product formed is:
\[ \text{KAg(CN)}_2 \]
This represents potassium argentocyanide.

### Step 6: Conclusion
Thus, the product obtained when Argentite is treated with potassium cyanide is:
\[ \text{KAg(CN)}_2 \]
