2N2 + 3H2 → 2NH3

Nitrogen and hydrogen gases react to form ammonia. Nitrogen gas is triple bonded between the atoms. Hydrogen gas and ammonia are single bonded between the atoms. Which bonds are in the reactants?

(1 point)

two N≡N and three N–H

two N≡N and three H–H

two N=N and three H–H

two N=N and three H≡H

Respuesta :

There are two N≡N bonds and three H–H  bonds are in reactants.

Given:

The reaction between nitrogen gas and hydrogen gas.

[tex]2N_2+3H_2\rightarrow 2NH_3[/tex]

To find:

Bonds on the reactant side

Solution:

[tex]2N_2+3H_2\rightarrow 2NH_3[/tex]

Reactants in the reaction = [tex]N_2, H_2[/tex]

The bond between nitrogen atoms in single [tex]N_2[/tex] molecule  = N≡N (triple bond)

Then in two [tex]N_2[/tex]  molecules = 2 N≡N (triple bonds)

The bond between hydrogen atoms in single [tex]H_2[/tex] molecule = H-H (single bond)

Then in three [tex]H_2[/tex]  molecules = 3  H-H (single bonds)

Product in the reaction =[tex]NH_3[/tex]

The bonds between nitrogen and hydrogen atoms in single [tex]NH_3[/tex] molecule = 3 N-H (single bond)

Then in two [tex]NH_3[/tex]  molecules = 6  N-H (single bonds)

So, there are two N≡N bonds and three H–H bonds are in reactants.
