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.

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
