Complete the table of bond energies and bond lengths.

need answer !

Explanation :

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

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

And bond energy is inversely proportional to the bond length.

If the more 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.

Order for bond length follows :

Order for bond energy follows :

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

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
