Water will dissolve into ethanol because water is nonpolar.
Oil will dissolve into ethanol because oil is polar too.
Oil will dissolve into ethanol because oil is nonpolar.
Table salt (NaCl) dissolves into water because...
table salt is polar and water is polar too.
table salt is ionic and water is polar.
table salt is nonpolar and water is nonpolar too.
table salt is ionic and water is nonpolar.
To dissolve more oxygen into water, one should...
decrease the pressure and increase the temperature.
increase the pressure and decrease the temperature.
increase the pressure and increase the temperature.
decrease the pressure and decrease the temperature.
Stirring a solution increases the rate of solvation because...
the process brings fresh solvent near the solute.
it increases the kinetic energy of the particles, which increases the solubility.
the process breaks the particles into smaller pieces.
it decreases the surface area of the solute particles.
