12. which of these would you expect to be soluble in the nonpolar solvent hexane, c6h14? a h2o b. ch, c naci d sns,

B. CH₄

Explanation:

The primary rule in deciding solubilities is, Like dissolves like. That is,

C₆H₁₄ is a nonpolar solvent. Its strongest intermolecular forces are London dispersion forces.

CH₄ is a nonpolar solute. It contains only nonpolar C-H bonds, and its strongest intermolecular forces are London dispersion forces.

Molecules of the two compounds can easily intermingle with each other because the attractive forces between them are so small.

A is wrong. H₂O is a highly polar substance. Its molecules are so strongly attracted to each other that they will not dissolve in the C₆H₁₄.

C and D are wrong. Both NaCl and SnS are compounds of a metal and a nonmetal. We would predict them to be ionic solids, at the extreme end of polarity. They  will not dissolve in C₆H₁₄.

if two electrons have the same n, the same ℓ, and the same ml, then they are in the same orbital. the pauli exclusion principle states that no two identical fermions (a fancy word for electrons and other subatomic particles like electrons) may occupy the same quantum state in an atom simultaneously.
