Question

49. Write the molecular equation for the following word equation.

$\mathrm{Nitrogen}+\mathrm{Hydrogen}\to \mathrm{Ammonia}$

Answer 1

Step 1:- Representation of elements

Nitrogen is denoted by N₂ and Hydrogen is denoted by H_{2 .}

Step 2:- Write the molecular equation

When nitrogen reacts with hydrogen, it produces ammonia (NH₃).

Therefore, the molecular equation can be written as:

$\underset{\mathrm{Nitrogen}}{{\mathrm{N}}_2\left(\mathrm{g}\right)}+\underset{\mathrm{Hydrogen}}{{\mathrm{H}}_2\left(\mathrm{g}\right)}\to \underset{\mathrm{Ammonia}}{{\mathrm{NH}}_3\left(\mathrm{g}\right)}$

After balancing the above reaction, the balanced molecular equation can be written as:

$\underset{\mathbf{Nitrogen}}{{\mathbf{N}}_{\mathbf{2}}\mathbf{\left(}\mathbf{g}\mathbf{\right)}}\mathbf{}\mathbf{}\mathbf{+}\underset{\mathbf{Hydrogen}}{\mathbf{3}{\mathbf{H}}_{\mathbf{2}}\mathbf{\left(}\mathbf{g}\mathbf{\right)}}\mathbf{}\mathbf{\to }\mathbf{2}\underset{\mathbf{Ammonia}}{{\mathbf{NH}}_{\mathbf{3}}\mathbf{\left(}\mathbf{g}\mathbf{\right)}}$
