The nitrogen compound formed when `NH_(4)NO_(3)` reacts with sodium hydroxide is

Options

A. `N_(2)H_(4)`
B. `N_(2)O`
C. `NH_(3)`
D. `NaNO_(3)`

Answer

To solve the problem of identifying the nitrogen compound formed when ammonium nitrate (NH₄NO₃) reacts with sodium hydroxide (NaOH), we can follow these steps:

### Step 1: Write the chemical reaction
When ammonium nitrate reacts with sodium hydroxide, the reaction can be represented as follows:

\[ NH_4NO_3 + NaOH \rightarrow ? \]

### Step 2: Identify the products of the reaction
In this reaction, ammonium nitrate (NH₄NO₃) reacts with sodium hydroxide (NaOH) to produce sodium nitrate (NaNO₃), ammonia gas (NH₃), and water (H₂O). The balanced equation for the reaction is:

\[ NH_4NO_3 + NaOH \rightarrow NaNO_3 + NH_3 + H_2O \]

### Step 3: Identify the nitrogen compounds formed
From the balanced equation, we can see that the nitrogen compounds formed are:
1. Sodium nitrate (NaNO₃)
2. Ammonia (NH₃)

### Step 4: Select the correct answer
The question asks for the nitrogen compound formed when NH₄NO₃ reacts with NaOH. The options provided were N₂H₄, N₂O, NH₃, and NaNO₃. The correct nitrogen compounds formed in this reaction are:
- Ammonia (NH₃)
- Sodium nitrate (NaNO₃)

Since the question asks for a nitrogen compound, both NH₃ and NaNO₃ are valid answers. However, since the question may imply a single answer, we can conclude that ammonia (NH₃) is the more direct product of the reaction.

### Final Answer:
The nitrogen compound formed when NH₄NO₃ reacts with sodium hydroxide is **ammonia (NH₃)**.
