- Q1Which of the following will dissolve the fastest in water?Large sugar cubes in hot waterPowdered sugar in hot waterLarge sugar cubes in cold waterPowdered sugar in cold water30s
- Q2Why is water considered an excellent solvent?It is a polar moleculeIt is a gas at room temperatureIt is nonpolarIt has strong covalent bonds30s
- Q3What type of intermolecular force is responsible for the strong attraction between water molecules?Hydrogen bondsIonic bondsDipole-dipole forcesDispersion forces30s
- Q4Which solution would likely conduct electricity the best?A solution of sugar in waterA concentrated solution of NaClA solution of ethanol in waterA dilute solution of NaCl30s
- Q5As temperature increases, what typically happens to the solubility of most solid solutes in water?It remains the sameIt increasesIt decreasesIt fluctuates randomly30s
- Q6Which compound is least likely to dissolve in water? (HINT: Look at the back of your periodic table)K₂SO₄NaClAgClNH₄NO₃30s
- Q7Why does a nonpolar solute like naphthalene dissolve in a nonpolar solvent like benzene?Because of the 'like dissolves like' principleBecause naphthalene is more soluble in waterBecause benzene has strong hydrogen bondingBecause benzene and naphthalene are both ionic30s
- Q8Why can a large number of water droplets fit on a penny before spilling over?The density of copperThe high solubility of waterThe cohesion between water moleculesThe presence of surface tension in air30s
- Q9A solution has weak electrical conductivity when tested. What can you conclude?The solute is completely insolubleThe solute is a strong electrolyteThe solution is highly concentratedThe solute is a weak electrolyte30s
