Consider the spontaneous dissolution of NaCl in
water NaCl(s) - Na (aq) + Cl(aq)
Predict whether the entropy change for this
process is positive or negative and explain your
answer.

Astable electron arrangement for an atom is one that does not easily change. how is this arrangement arrived at? a. valence electrons are transferred or shared to create a full outer shell of electrons. b. valence electrons are discarded into space to create a full outer shell of electrons. c. protons (positive charge) pair with valence electrons (negative charge) to create a strong bond. d. outer shells with valence electrons are transferred or shared.
