Question

how can you represent two molecules of ammonia​

Answer 1

Answer:

The representation of two moles of ammonia is

$2 N_{2}+3 H_{2} \rightarrow 2 N H_{3}$

Explanation:

• This shows that ammonia exists as diatoms. As it is known, Nitrogen has 5 valence electrons and hydrogen has 1 electron in its outer shell. Thus, nitrogen requires three more electrons to complete the octet structure, while hydrogen needs only 1 electron to become a stable atom.
• To achieve this, nitrogen shares three of its electrons with three hydrogen atoms. This leaves two electrons as lone pair. Thus, an$\mathrm{NH}_{3}$ molecule contains three N-H single covalent bonds and a single pair of electrons on the nitrogen atom.
• This separate pair of electrons of one $\mathrm{NH}_{3}$ is shared with the lone pair of another $\mathrm{NH}_{3}$ molecule to form a stable compound.
