| Question | Answer |
|---|---|
| Some interchangeable terms that indicate looking at H bonding | Hydrophilic/attracted to water region soluble in water |
| What components support greater attraction due to H bonding in a solution? | 1) Hydrogen bonded to N, O, F (those highly electronegative atoms) 2) A lone pair of electrons on N, O, or F |
| What makes something more or less soluble in water | the number of H bonds it's able to make "the greater number of attractions, the more soluble the molecule will be in water" |
| molality | mol solute/kg solvent |
| solute | lesser concentration in an aq solution, the thing that isnt water |
| solvent | the one theres more of in an aq solution, this is water |
| mol fraction | MOLS solute/total MOLS NOT GRAMS DONT FORGET TO CONVERT!! its easy as long as you remember that |
| reaction rate | change in concentration over change in time we can talk about reaction rate with respect to compoud A, B, C, etc ex: rxn rate with respect to Zn2+ [Zn2+]/t |
