Balance the following chemical equations and identify the type of chemical reaction.
`Na(s) + S(s) overset("Fuse")to Na_(2)S(s)`

Explanation

To balance the given chemical equation and identify the type of chemical reaction, follow these steps:

### Step 1: Write the unbalanced equation
The unbalanced equation is:
\[ \text{Na(s)} + \text{S(s)} \rightarrow \text{Na}_2\text{S(s)} \]

### Step 2: Count the number of atoms of each element on both sides
- **Reactants:**
