6) A student massed a 0.1876 g sample of sodium oxalate (Na2C204) and added it to an Erlenmeyer flask with 50.00 mL of water. After dissolving the sample, it was then titrated with 43.77 mL of KMnO4 (aq) according to the following reaction:
5Na2C2O4(aq) + 2KMnO4(aq) + 8H2SO4(aq) → 2MnSO4(aq) + K2SO4(aq) + 5Na2SO4(aq) + 10CO2(g) + 8H20m)
Find the molarity of the KMnO4 solution in the buret.

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?
