Give the equations for the conversion of argentite `(Ag_2S)` to metallic silver.

Explanation

To convert argentite (Ag₂S) to metallic silver, we can follow a series of chemical reactions. Here is the step-by-step solution:

### Step 1: Reaction of Argentite with Sodium Chloride
Argentite (Ag₂S) reacts with sodium chloride (NaCl) to form sodium di-sino-arginato and sodium sulfide (Na₂S).

**Equation:**
\[ \text{Ag}_2\text{S} + 2 \text{NaCl} \rightarrow \text{Na}_2[\text{Ag(CN)}_2] + \text{Na}_2\text{S} \]
