Would a photon whose wavelength is 230 nm have enough energy to photodissociate o2 whose bond energy is 495 kj/mol? would it have enough energy to photoionize o2? match the words in the left column to the appropriate blanks in the sentences on the right.

Yes, a wavelength of 230 nm can photo ionize O2.

Explanation:

Wavelength, λ = 230 nm = 230 ×

Bond disassociation energy per mole = 495 kJ/mol

Bond disassociation energy per molecule =

= 8.22×

Wavelength associated with this bond energy is, =

=

= 242 nm

Therefore, any wavelength shorter than 242 nm can photo ionize O2.

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.

a small object of mass 3.66 g and charge -17.6 µc is suspended motionless above the ground when immersed in a uniform electric field perpendicular to the ground. what are the magnitude and direction of the electric field?
