8. An excited Hydrogen atom in the n=3 energy level decays to the n=2 energy level and emits a photon of light. If the energies of these two levels are separated by
3.029 x 10-19 J, what will be the wavelength of the light emitted in nanometers?

The human eye contains a molecule called 11-cis-retinal that changes shape when struck with light of sufficient energy. the change in shape triggers a series of events that results in an electrical signal being sent to the brain that results in vision. the minimum energy required to change the conformation of 11-cis-retinal within the eye is about 164 kj/mol.

Water is initially present in a state where its molecules are far apart. during a change of state, its molecules slow down. which change of state has most likely taken place? from a gas to a liquid from a liquid to a gas from a solid to a liquid from a gas to a plasma
