If NaCl dissolves in water. Which of the following is true when considering that water is polar and the hydrogen (Mickey Mouse Ears) are partially positively charged and the oxygen is partially negatively
charged

Consider hydrogen in an excited state n = 5n=5 that emits photons to reach the ground state. there are various possible transitions other than straight to the ground state that can occur; for example, it can drop to the n = 3n=3 state followed by the n = 3n=3 to the ground state transition. which of the possible transitions will result in the emission of a photon in the visible region?
