Question

What is the molecular formula of the compound of nitrogen and hydrogen both are diatomic?.

Answer 1

We know that the molecular formula is a portrayal of a particle that utilizes compound images to demonstrate the sorts of iotas followed by addendums to show the quantity of molecules of each kind in the particle. An addendum is utilized just when more than one iota of a given sort is available. Molecular formula is additionally utilized as truncations for the names of mixtures.

Complete answer:
We have to remember that the compounds are shaped when at least two components synthetically consolidate, bringing about the development of bonds. For instance, hydrogen and oxygen can respond to shape water, and sodium and chlorine can respond to frame table salt. We in some cases portray the arrangement of these mixtures with an empirical formula, which shows the kinds of particles present and the easiest entire number proportion of the quantity of iotas (or particles) in the compound.
Let us calculate the number of moles of nitrogen and hydrogen,
We know that nitrogen is a hypotenuse diatomic molecule,
The number of moles of nitrogen can be calculated as follows,
$N = \dfrac{{88}}{{2(14)}} = 3.14$
The number of moles of hydrogen can be calculated as follows,
$H = \dfrac{{12}}{{2(1)}} = 6$
Divide the number of moles of nitrogen and hydrogen by the smallest number,
$N = \dfrac{{3.14}}{{3.14}} = 1$
$H = \dfrac{6}{{3.14}} = 2$

The ratio of nitrogen and hydrogen is $1:2$. Thus the molecular formula of the compound is ${N_2}{H_4}$ hence option b is correct.

Note:
We also remember that the diamine or Diazane or Nitrogen hydride are the other names of hydrazine and is a solid base. It is an azane and perilously unsteady. Every subunit of ${H_2}N - N$ is pyramidal and the $N - N$ bond distance is about $1.45{\text{ }}{\mathop A\limits^ \circ}$.
Diamine in its anhydrous structure is a boring, raging slick fluid which scents like alkali. It has a glimmer point worth of $99^\circ F$. On the off chance that if hints of air is available during the interaction of refining, it detonates. It is poisonous and destructive to tissues. At the point when it goes through ignition, it produces poisonous oxides of nitrogen.
