Answer: 8500 J lost or -8500 J
Explanation:
q=cmt
t=375-26
t=349
q=0.38(64)(349)
q=8487.68 J
Answer must have 2 sig figs, which means it rounds to 8500 J.
Explanation:
<em>When the electron changes levels, it decreases energy and the atom emits photons. The photon is emitted with the electron moving from a higher energy level to a lower energy level. The energy of the photon is the exact energy that is lost by the electron moving to its lower energy level.</em>
The answer to the question stated above is:
