Question

Balance
__N/+H2->NH3

Answer 1

To balance the chemical equation for the reaction between nitrogen (N) and hydrogen (H₂) to form ammonia (NH₃), follow these steps:

1. Write the unbalanced equation:
\[
\text{N} + \text{H}_2 \rightarrow \text{NH}_3
\]

2. Count the number of atoms of each element on both sides of the equation:
- Reactants:
- Nitrogen (N): 1
- Hydrogen (H): 2
- Products:
- Nitrogen (N): 1
- Hydrogen (H): 3

3. To balance the equation, note that there are 3 hydrogen atoms in the ammonia product but only 2 in the reactants. To balance the hydrogen atoms, you can adjust the coefficient in front of H₂.

4. Since 3 hydrogen atoms are needed, you can use \(\frac{3}{2}\) for H₂:
\[
\text{N} + \frac{3}{2}\text{H}_2 \rightarrow \text{NH}_3
\]

5. Alternatively, you can multiply the entire equation by 2 to eliminate the fraction:
\[
2\text{N} + 3\text{H}_2 \rightarrow 2\text{NH}_3
\]

Now, the balanced equation reads:
\[
2\text{N} + 3\text{H}_2 \rightarrow 2\text{NH}_3
\]

This balanced equation indicates that 2 molecules of nitrogen react with 3 molecules of hydrogen to produce 2 molecules of ammonia.
