In each blank, try to type in the
word that is missing. If you've
typed in the correct word, the
blank will turn green.
If your not sure what answer should be entered, press the space bar and the next missing letter will be displayed. When you are all done, you should look back over all your answers and review the ones in red. These ones in red are the ones which you needed help on. Term: propertiesDescription: Vapor-pressure depression (boiling-point elevation), -point depression, osmotic pressure. Term: solubilityDescription: The amount of that will saturate a particular solvent. Term: molalityDescription: Moles of solute per of solvent Term: mole Description: Moles of solute over moles of solution Term: dissolve best in solvents...Description: ... the intermolecular forces being broken in the solute are being replaced by equal or stronger forces between the solvent and the solute. Term: Molality is because...Description: ... it is independent of and pressure. Term: strong Description: substances that dissociate completely Term: weak Description: Ionic compounds that do not completely Term: Strong ...Description: ...conduct better than weak electrolytes. Term: van't Hoff Description: ("i") The number of ions a unit of a will produce in a given solution. (Ex: For NaCl, i = 2) Term: Description: ("i") See van't Hoff . Term: All ionic ...Description: ... are strong , whether soluble or not. Term: Solubility of in water (1)Description: All Group I (Li, Na, K, Rb, Cs) and ammonium salts are . Term: Solubility of salts in (2)Description: All nitrate (NO3-), perclorate (ClO4-), and (C2H3O2-) salts are soluble. Term: Solubility of in water (3)Description: All silver, lead, and salts are insoluble (except for compounds soluble under rule 2). Term: solubility (1)Description: The of solids in liquids tends to increase with increasing temperature. Term: Phase (2)Description: The solubility of gases in liquids tends to decrease with temperature. Term: solubility (3)Description: The solubility of gases in liquids tends to increase with pressure. Term: Colligative ...Description: are only dependent on the number of particles in the solution, and are of the identity of particle. Term: pressureDescription: The pressure exerted by the gaseous phase of a liquid that evaporated from the exposed of the liquid. Term: Description: Having high pressure. Term: boiling Description: The at which the vapor pressure of a solution is equal to atmospheric pressure. Term: Salt ...Description: ... has a lower vapor pressure and boils at a higher temperature than pure . Term: Raoult's Description: The partial vapor pressure of a particular substituent in a solution is proportional to its mole . Term: Dalton's Description: The total vapor pressure over a solution is the sum of the vapor pressures of the substituent liquids. Term: vapor-pressure Description: Change in partial pressure of a solution due to of nonvolatile solute B into solvent A is equal to the negative product of the mole fraction of B and the partial pressure of pure A. Term: ideal Description: A solution where all intermolecular forces are . Term: Vapor-pressure depression because...Description: ... dissolution of a solute in a solvent closes the entropy gap between the soution and vapor phases. The smaller in entropy from evaporation leads to less tendency to evaporate. Occurs only in solid-liquid solutions. Term: Boiling point elevation occurs ...Description: ... when vapor pressure is depressed, higher temperature is needed to vaporize the solution. in only solid-liquid solutions. Term: The of a liquid-liquid solution deviates from Raoult's Law when...Description: ... (1) forces between the liquids are weaker (resulting in higher vapor pressure); (2) Intermolecular forces are stronger (resulting in lower vapor pressure). Term: boiling-point Description: = (k)(i)(m); k = 's boiling point elevation constant, i = solute's van't Hoff factor, m = molality of the solution Term: Freezing-point occurs because...Description: ... soluting a solvent increases the entropic difference between the solution and phases (making things easier to melt and harder to freeze). Occurs in both solid-liquid and liquid-liquid solutions. Term: freezing-point Description: = -(k)(i)(m) Term: osmotic Description: = Term: force exerted by a Description: F = -kx Term: elastic potential Description: E = (1/2)kx^2 Term: frequency of a oscillating on a springDescription: f = (1/2pi)sqrt(k/m) Term: of a block oscillating on a springDescription: T = 1/f Term: A undergoes...Description: ... not simple harmonic motion. When the angle is small, though, it acts like a harmonic. Term: frequency of an pendulumDescription: f = (1/2pi)sqrt(g/L). (Note: only applies to angles.) Term: wave Description: = (wavelength)(frequency) Term: wave on a ropeDescription: = sqrt(T/D); T = tension, D = density Term: Wave depends on...Description: ... the type of wave and the characteristics of the medium, and not the frequency. through a material medium is the only exception. Term: When a wave into a different medium...Description: ... changes, but not frequency. Term: The of a wave depends on...Description: ... energy, not , wavelength, or wave speed. Term: Description: The first harmonic, whose wavelength is the length of the rope |
