Calcule el porcentaje de rendimiento (%R) de la siguiente reacción química: N2 + O2 ? N2O5 Si se hace reaccionar 85 g de N2 al 65% con 95 g de O2 al 74% y se obtienen experimentalmente 82 g de N2O5.

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?
