The combustion of 0.5 moles of a substance increases the temperature of a bomb calorimeter from 22.73 o C to 26.95 o C. The calorimeter has a heat capacity of 2.82 kJ/o C. Determine the heat of combustion per mole of substance.

In the space, show a correct numerical setup for calculating the number of moles of co2 present in 11 grams of co2

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?
