Which best explains what happens when an electron moves from an excited state to the ground state? the electron absorbs energy as it moves to a lower energy level. the electron absorbs energy as it moves to a higher energy level. the electron releases energy as it moves to a higher energy level. the electron releases energy as it moves to a lower energy level.

If you want to create an electrical current, which situation would produce a solution capable of this

1) in saturated limewater, [h+ ]=3.98x10-13 m. a) find [oh]-/ b) what is the ph? / c) is the solution acidic, basic, or neutral? / 2) in butter, [h+ ]=6.0x10-7 m. a) find [oh]-/ b) what is the ph? / c) is the solution acidic, basic, or neutral? / 3) in peaches, [oh]=3.16x10-11 m a) find [h+ ]/ b) what is the ph? / c) is the solution acidic, basic, or neutral? / 4) during the course of the day, human saliva varies between being acidic and basic. if [oh]=3.16x10-8 m, a) find [h+ ]/ b) what is the ph? / c) is the solution acidic, basic, or neutral? /

As changes in energy levels of electrons increase, the frequencies of atomic line spectra they emit
