The bonds of oxygen molecules are broken by sunlight. the minimum energy required to break the oxygen-oxygen bond is 495 kj/mol o2. what wavelength of sunlight is required to break the bond in one o2 molecule?

The wavelength of sunlight is required to break the bond in one oxygen molecule is 242 nm.

Explanation:

Energy required to break the 1 mol oxygen-oxygen bond:

=495 kJ=495000J

1 mol = molecules

Energy required to break 1 molecule of oxygen molecule= E

=

The energy required to break the  1 molecule of oxygen is equal to enrgy of one photon of a sunlight.

where,

= wavelength of the light

E = energy of the photon

h = Planck's constant =

c = speed of light =

The wavelength of sunlight is required to break the bond in one oxygen molecule is 242 nm.

nacl is added to the aqueous of what? ? in order to get a proper answer you have to specify the exact composition of the aqueous solution.

i think it's c. i'm not sure but i think so.
