  • D. Solvent


Chemistry jeopardy unit 6

  • This factor has the largest effect of the solubility of solid compounds.

  • Pressure

  • Temperature

  • Rate of Stirring

  • Amount of solvent


Chemistry jeopardy unit 6

  • A solution that contains the maximum amount of solute possible.

  • Unsaturated

  • Saturated

  • Supersaturated

  • Megasaturated


Chemistry jeopardy unit 6

  • To maximize the solubility of gases in solutions a student should.

  • Increase the temperature

  • Decrease the temperature

  • Decrease the pressure

  • Increase the amount of solvent


Chemistry jeopardy unit 6

  • What saying allows us to predict if a solvent will dissolve a solute?

  • Likes dissolve likes

  • Polar dissolves nonpolar

  • Nonpolar dissolves polar

  • All solvents dissolve all solutes


Chemistry jeopardy unit 6

  • Molarity has units of

  • grams/mole

  • moles/kilogram

  • liters/mole

  • moles/liter


Chemistry jeopardy unit 6

  • What is the concentration of a solution made by dissolving 1.5 mol of NaCl to a volume of 500. mL

  • 1.5 M

  • 0.0030 M

  • 3.0 M

  • 2.0 M


Chemistry jeopardy unit 6

  • The product of concentration times volume.

  • Moles

  • Molarity

  • Keq

  • Dilution


Chemistry jeopardy unit 6

  • Proper solution preparation requires what piece of equipment.

  • Beaker

  • Erlenmeyer Flask

  • Graduated Cylinder

  • Volumetric Flask


Chemistry jeopardy unit 6

  • What is the resulting concentration when 20. mL of a 2.0M solution is diluted to 40. mL?

  • 1.0 M

  • 0.50 M

  • 2.0 M

  • 4.0 M


Chemistry jeopardy unit 6

  • Colligative Properties depend on the number of

  • Chemists Working

  • Particles in solution

  • Beakers used

  • Readings taken


Chemistry jeopardy unit 6

  • A liquid reaches its boiling point when

  • It feels like it

  • When bubbles start form

  • The vapor pressure of the liquid equals the pressure of the atmosphere

  • Cannot be determined


Chemistry jeopardy unit 6

  • Adding a solute to a solvent

  • Raises the freezing point

  • Lowers the boiling point

  • Lowers the freezing point

  • Does not change the boiling point


Chemistry jeopardy unit 6

  • What is the advantage of using AlCl3 to melt ice on sidewalks as opposed to NaCl

  • A. The freezing point change will be 2x larger

  • The freezing point change will be 4x larger

  • The freezing point change will be 10x larger

  • There is no advantage


Chemistry jeopardy unit 6

  • When ΔTf = 3.4 ºC for an aqueous solution of NaCl the new freezing point of the solution is

  • 3.4 ºC

  • -3.4 ºC

  • 103.4 ºC

  • 96.6 ºC


Chemistry jeopardy unit 6

  • When a reaction reaches equilibrium the forward and reverse reactions

  • Occur at different rates

  • Occur at the same rate

  • Stop

  • Make the same amount of chemical


Chemistry jeopardy unit 6

  • The only stress that can change the equilibrium constant is

  • Concentration

  • Temperature

  • Pressure

  • Final Exams


Chemistry jeopardy unit 6

  • A large equilibrium constant mean the reaction is

  • Product favored

  • Reactant favored

  • Neutral

  • Happens very fast


Chemistry jeopardy unit 6

  • Ksp expressions are written for

  • Chemical equilibrium

  • Force equilibrium

  • Solubility equilibrium

  • Balance Equilibrium


Chemistry jeopardy unit 6

  • When a common ion is added to an equilibrium the equilibrium shifts

  • Toward the added ion

  • Away from the added ion

  • Toward the heat in the reaction

  • Toward the higher pressure


Chemistry jeopardy unit 6

  • What is the equilibrium expression for the following equation?

  • 3A(g) + 2B(g) A3B2(g)

  • Keq = [A3B2] / ([A]3[B]2)

  • Keq = [A]3 [B]2 / [A3B2]

  • Keq = [A] [B] / [A3B2]

  • Keq = [A3] [B2] / [A3B2]


Chemistry jeopardy unit 6

  • How can the following reaction be

  • made to favor the product side

  • of the reaction?

  • 3A(g) + 2B(g)  A3B2(g) + heat

  • Add more product

  • Increase the pressure

  • Increase the temperature

  • Add a catalyst


Chemistry jeopardy unit 6

  • What is the Ksp expression for the following reaction

  • BaSO4(s)  Ba+2 + SO4-2

  • Ksp = [BaSO4] / ([Ba+2] [SO4-2])

  • Ksp = [Ba+2] [SO4-2] / [BaSO4]

  • Ksp = [BaSO4] / [Ba]2 [SO4] -2

  • Ksp = [Ba+2] [SO4-2]


Chemistry jeopardy unit 6

  • Which of the following will have no effect on the reaction?

  • A (g) + B (g) AB (g) + heat

  • Increasing the amount of A

  • Decreasing the temperature

  • Increasing the amount of A2B2

  • Increasing the pressure


Chemistry jeopardy unit 6

  • How could you lower the concentration of Ba+2 for the following reaction?

  • BaSO4(s) Ba+2 + SO4-2

  • Add solid Na2SO4

  • Increase the pressure

  • Add solid Ba(NO3)2

  • The concentration cannot be changed
