Magnesium nitride reacts with water giving

Options

A. `NO_2`
B. `N_2 O_3`
C. `NH_3`
D. `NO`

Explanation

To solve the question regarding the reaction of magnesium nitride with water, we will follow these steps:

### Step 1: Write the chemical formula for magnesium nitride.
Magnesium nitride is represented by the formula \( \text{Mg}_3\text{N}_2 \).

### Step 2: Write the chemical equation for the reaction with water.
When magnesium nitride reacts with water, it produces magnesium hydroxide and ammonia. The unbalanced equation can be written as:
\[ \text{Mg}_3\text{N}_2 + \text{H}_2\text{O} \rightarrow \text{Mg(OH)}_2 + \text{NH}_3 \]

### Step 3: Balance the chemical equation.
To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides. The balanced equation is:
\[ \text{Mg}_3\text{N}_2 + 6\text{H}_2\text{O} \rightarrow 3\text{Mg(OH)}_2 + 2\text{NH}_3 \]

### Step 4: Identify the products of the reaction.
From the balanced equation, we can see that the products of the reaction are:
- Magnesium hydroxide (\( \text{Mg(OH)}_2 \))
- Ammonia (\( \text{NH}_3 \))

### Conclusion:
Thus, when magnesium nitride reacts with water, it produces magnesium hydroxide and ammonia.
