Chemistry teacher puts 5 mL of water into a soft plastic pop bottle and, with tongs, holds it in a hot water bath for 1 minute. The teacher removes the bottle and tightly screws on the cap. Use the Kinetic Molecular Theory to explain the predicted observation.

When hydrochloric acid reacts with potassium hydroxide solution, the following reaction occurs. hcl (aq) + koh (aq) h2o (l) + kcl (aq) the reaction gives off heat energy, so it is an reaction.

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?
