I NEED HELP PLEASE! :)

Describe the energy change when an electron moves from one energy level in an atom to another, both to a higher energy state and to a lower energy state. Tell whether a photon is absorbed or released in each case.

See explanation

Explanation:

When an electron moves from a high energy state to a lower one, the energy state decreases and the atom releases a photon. Conversely, when an electron moves to a higher energy state, it absorbs a photon. Hope this helps!

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"
