Complete the reactions
`NH_3 + O_2 overset"Pt" to`

Explanation

To complete and balance the reaction between ammonia (NH₃) and oxygen (O₂) in the presence of platinum (Pt), we follow these steps:

### Step 1: Write the Unbalanced Reaction
Start by writing the unbalanced equation for the reaction:
\[ \text{NH}_3 + \text{O}_2 \xrightarrow{\text{Pt}} \text{NO} + \text{H}_2\text{O} \]

### Step 2: Identify Products
When ammonia reacts with oxygen, it forms nitrogen monoxide (NO) and water (H₂O). So, we can write the products as:
