Help, I thought I got an answer to this, but I feel like it's wrong based on the theoretical Molar Enthalpy of Napahthalene given: -5155.9kJ/mol. What would be the steps in solving this?

Given 7.65 g of butanoic acid and excess ethanol, how many grams of ethyl butyrate would be synthesized, assuming a complete 100% yield?

The boiling point of liquids is very high what does it indicate

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?
