ammonium hydroxide ionizes as follows: nh4oh nh4+ + oh-. if an excess of ammonium salt, such as nh4cl (which ionizes to give nh4+ ions), is added to the equilibrium shown above, you could predict that the result will be to:

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?
