1Matter CANNOT be a mixture, it can obly be a pure substance
- ATrue
- BFalse
2Substances have [blank_start]definite compositions[blank_end] and [blank_start]uniform properties[blank_end]
- Adefinite compositions
- Buniform properties
3[blank_start]ELEMENTS[blank_end] are substances made of only one kind of atom; can't be chemically changed/separated
[blank_start]COMPOUNDS[blank_end] formed when atoms of two or more elements combine chemically- ACOMPOUNDS
- BELEMENTS
- CCOMPOUNDS
- DELEMENTS
4[blank_start]HOMOGENOUS MIXTURES[blank_end]
- aka solutions
- Uniform properties within the sample
- Appear as only one phase
[blank_start]HETEROGENOUS MIXTURES[blank_end]
- Non-uniform properties
- Components usually separate into distinct regions
- e.g. suspensions and colloids- AHOMOGENOUS MIXTURES
- BHETEROGENOUS MIXTURES
5[blank_start]SUSPENSIONS[blank_end]
- Mixtures whose parts havd enough weight diff.
- Easily separate by decantation
[blank_start]COLLOIDS[blank_end]
- Mixtures that appear fo be homogenous
- Exhbits Tyndall Effect
- Sometimes appear cloudy- ACOLLOIDS
- BSUSPENSIONS
- CCOLLOIDS
- DSUSPENSIONS
6What do you call this effect?
- ATyndall Effect
7Which mixture is a solution?
- AA 50:50 mixture of ethyl alcohol and water
- BCarbonated water in fizzy drinks
- CCopper and tin in bronze
- DAll of the above
8The state of the solution is not dependent on the state of the solvent
- ATrue
- BFalse
9[blank_start]SOLUTE[blank_end] is the dissolved substance
[blank_start]SOLVENT[blank_end] is the dissolving medium- ASOLUTE
- BSOLVENT
- CSOLUTE
- DSOLVENT
10[blank_start]SATURATION CONCENTRATION[blank_end] is the extent of Solubility
- ASATURATION CONCENTRATION
- BUNSATURATED SOLUTION
- CSUPERSATURATED SOLUTION
- DSATURATED SOLUTION
11Factors affecting solubility:
- ANature of Solute and Solvent
- BTemperature
- CPressure
- DStirring/Agitiation
- ESize of Solute (Surface Area)
12Nature of Solute and Solvent:
Nonpolar Solvents dissolve Polar & Ionic Solutes- ATrue
- BFalse
13Temperature:
Gasses occupy more space when temperature is increades making it harder to mix w/ the solvent- ATrue
- BFalse
14Pressure:
[blank_start]Henry's[blank_end] Law states that solubility of a gas increases with partial pressure of the gas above the liquid
>> pressure makes the solvent dissolve the compressed solute easier- AHenry's
15Factors affecting dissolution:
- ANature of Solute and Solvent
- BTemperature
- CPressure
- DStirring/Agitation
- ESize of Solute/Surface Area
16[blank_start]CONCENTRATION[blank_end] is the relative amt of solute contained in a solution
- ACONCENTRATION
17What are reactive solutions?
- AAcids
- BBases
18[blank_start]BASES[blank_end]
- pH > 7 and pOH < 7
- usually tastes bitter
- turns red litmus paper blue
- aqueous oxides of metals are usually this
[blank_start]ACIDS[blank_end]
- pH < 7 and pOH > 7
- blue litmus paper -> red
- aqueous oxides of nonmetals are usually this- ABASES
- BACIDS
19The lower the pH (potential of Hydrogen), the more acidic the solution is
- ATrue
- BFalse
20[blank_start]NEUTRALIZATION REACTIONS[blank_end]
- type of double displacement reaction wherein the products of the acid and the base are H2O and salt (an ionic compound)- ANEUTRALIZATION REACTIONS
