Find the longest wavelengths of light that can cleave the bonds in elemental nitrogen, oxygen, and fluorine. the average bond energy of n―n bond is 945 kj/mol, oxygen is 498 kj/mol, and f―f is 159 kj/mol. give your answers in scientific notation.

Explanation:

Longest wavelengths of light that can cleave the bonds in elemental nitrogen

Energy to cleave 1 mol N-N bond = 945 kJ/mol = 945000 J/mol

1 mol=

Energy to break 1  N-N bond =

Longest wavelengths of light that can cleave the bonds in elemental nitrogen is 127.4 nm.

Similarly

For oxygen:

Energy to cleave 1 mol O-O bond = 498 kJ/mol = 498000 J/mol

Energy to break 1  O-O bond =

Longest wavelengths of light that can cleave the bonds in elemental oxygen is 240.6 nm.

For fluorine

Energy to cleave 1 mol F-Fbond = 159 kJ/mol = 159000 J/mol

Energy to break 1  F-F bond =

Longest wavelengths of light that can cleave the bonds in elemental fluorine is 752.9 nm.
