Each group wants to have 8 valence electrons in order to be “happy” which means chemically stable. The goal is to be just like the Noble Gas family who already have 8
valence electrons. So what is the easiest thing for each group to do in order to be
"happy"?

Apure solvent has a vapor pressure the vapor pressure of a solution. a. equal to b. lower than c. higher than

Compare and contrast physical changes with chemical changes.

Many free radicals combine to form molecules that do not contain any unpaired electrons. the driving force for the radical–radical combination reaction is the formation of a new electron‑pair bond. consider the chemical equation. n(g)+no(g)⟶nno(g) n(g)+no(g)⟶nno(g) write lewis formulas for the reactant and product species in the chemical equation. include nonbonding electrons. n(g)n(g) select draw rings more erase select draw rings more erase select draw rings more erase n no(g)
