Respuesta :

Answer: The reactants (initial) contain 6 atoms of hydrogen and 2 atoms of nitrogen

The products (final) contain two atoms of nitrogen and six atoms of hydrogen

The number of atoms is the same in the initial and final boxes

Explanation:

Atom is the smallest unit of an element which may or may not exist independently.

Molecule is the smallest unit of a pure substance that consists of two or more atoms held together by a chemical bond .

Molecule of a Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass.  Example:  [tex]NH_3[/tex]

Molecule of an element is a pure substance formed by combination of same types of atoms bonded by a chemical bond. Example: [tex]H_2[/tex] and [tex]N_2[/tex]

Here one molecule of nitrogen ([tex]N_2[/tex]) combines with 3 molecules of hydrogen ([tex]H_2[/tex]) to give 2 molecules of ammonia. ([tex]NH_3[/tex]).
