Complete the table of bond energies and bond lengths.

need answer !

Explanation:

N-n : 167 (energy) 145 (length)

N=n : 418 (energy) 125(length)

N (three lines)n : 942 (energy) (110) length

(not sure if I’m too late but I asked my teacher and she looked at the answer sheet so it’s correct )

Answer : The complete table of bond energies and bond lengths are shown below.

Explanation :

Bond length : It is the average distance present between the nuclei of two bonded atoms in the molecule.

Bond energy : It is the amount of energy required to break the molecules into its components atoms.

The relation between the bond energy and the bond length is :

The bond energy is inversely proportional to the bond length.

If more the number of bonds are formed between the atoms, that means the bond strength of that bond will be more or the bond length will be less and the bond energy will be more.

Thus, single bond have the highest bond length and lower bond energy.

Then, double bond has the lowest bond length than the single bond length and higher bond energy than the single bond energy.

Then, triple bond has the lowest bond length than the double bond length and higher bond energy than the double bond energy.

Order for bond length follows :

Order for bond energy follows :

The complete table of bond energies and bond lengths are shown below.

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.
