100
A bowl of soup with chunks of meat and tomato vs a bottle of Gatorade
What is a heterogenous vs a homogenous mixture?
100
Increasing temperature generally increases the solubility of these substances in water.
What are solids?
100
The molarity when there's two moles of KMnO4 and one liter of water in solution
What is 2.0M?
100
The solution with the lowest solubility after 20 degrees
What is Ce2(SO4)3?
100
Adding salt to water raises this property.
What is the boiling point?
200
The way to drive off the H20 molecules bonded to a hydrate
What is heating?
200
Increasing pressure increases the solubility of these substances in liquids.
What are gases?
200
The molarity of a solution made by dissolving 1.2 mol of KNO₃ in 400 mL of solution.
What is 3.0 M?
200
Decreases as temperature increases
What is the solubility of Ce2(SO4)2?
200
The boiling point of a solution is generally this compared to pure water.
What is higher?
300
Dissolves best when cold and under high pressure
What is a gas?
300
Because of this, oils can dissolve in each other but can't dissolve in water
What is polarity?
300
The percent concentration when 4.6 g of NaCl are dissolved in 22 mL of water
What is 17%?
300
The solution with the greatest conductivity at 80 degrees
What is KNO3?
300
K+ and MnO4 particles sit at the surface of the solution, preventing H2O from evaporating
What is vapor pressure lowering?
400
The state of solution when a portion of a sample of KMnO4 is stops dissolving
What is equilibrium?
400
The forces keeping a NaOH crystal together are weaker than the forces of the water molecule pulling it apart
What is solvation?
400
The mole fraction of a solution with 20g of NaCl and 50 mL of water
What is .11?
400
The solution with the lowest change in solubility from 20 to 40 degrees
What is NaCl?
400
Salt spread on icy roads works primarily by causing this effect.
What is freezing-point depression?
500
Stirring, the surface area of the particles, and the temperature of solution
What affect solution formation?
500
The most conductive out of CH4, Ba(OH)2, and NaCl.
What is Ba(OH)2?
500
The molality when .17 moles of KOH are mixed with 20 mL of H20
What is .5 molality?
500
It makes H20 molecules move faster, making them collide with KNO3 molecules with greater force, which breaks them apart in K+ and NO3- ions at a greater rate
Why does heating a KNO3 solution increase it's solubility?
500
The greatest freezing point depression out of 1.0 M glucose, 1.0 M NaCl, or 1.0 M CaCl₂.
What is 1.0 M CaCl₂?
