What challenges did you encounter during the circuit training program?

The dissociation energy of a molecule is the energy required tobreak apart the molecule into its separate atoms. the dissociationenergy for a particular molecule is 5.48 x 10-18 j.suppose that this energy is provided by a single photon. determinethe (a) wavelength and (b) frequency of the photon

F500 j of energy were added to 1 kg of each of these samples, which would experience the least temperature increase?
