Silver tarnishes in the presence of oxygen and hydrogen sulfide according to the following equation:
4Ag(s) + 2H_S(g) + O2(g) → 2Ag, S(s) + 2H2O(1)
tarnish
Usually, H, S is the limiting reactant. If a silver spoon is placed in a container
that holds 62.1 mL of H, S at 1.15 atm and 23.0°C, how many grams of silver
on the spoon will tarnish?

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?
