Balance the following chemical equation
`Na+H_2OtoNaOH+H_2`

Explanation

To balance the chemical equation \( \text{Na} + \text{H}_2\text{O} \rightarrow \text{NaOH} + \text{H}_2 \), we will follow these steps:

### Step 1: Write down the unbalanced equation
The unbalanced equation is:
\[ \text{Na} + \text{H}_2\text{O} \rightarrow \text{NaOH} + \text{H}_2 \]

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