|
||||
|---|---|---|---|---|---|
| How does the vapor pressure of water compare with most volatile liquids? | Vapor pressure of water is significantly lower
🗑
|
||||
| What is volatile liquids? | gasoline; goes into gas form easily
🗑
|
||||
| What is the best way to determine if a solution is an electrolyte? | does it conduct electricity
🗑
|
||||
| If electricity is not conducted through a solid compound but is conducted when the solid is dissolved(molten) what is the compound? | electrolyte
🗑
|
||||
| Why does ice float on liquid water? | hydrogen bonding causes water molecules in ice to be held apart in an orderly arrangement
🗑
|
||||
| How are water molecules arranged in ice? | in a framework of hexagonal shapes
🗑
|
||||
| Which types of compounds are usually electrolytes? (give example) | salts; examples: sodium chloride, lithium chloride, and lithium nitrate; (Groups 1,2,3 + Groups 5,6,7, or polyatomics )
🗑
|
||||
| What is the difference in O to H(water) and C to H bonds(volatile)? | Hydrogen bonding is stronger among the water molecules than methane
🗑
|
||||
| How does hydrogen bonding account for the properties of water? | increases the attractive force among water molecules; allows water to exist in a liquid state among different temperatures
🗑
|
||||
| How does a suspension differ from a solution? | particles of a suspension are much larger and do not stay suspended
🗑
|
||||
| Why do hydrate easily gain and lose water? | because there's a relatively weak force that holds water molecules within the hydrate
🗑
|
||||
| What effect do surfactants have on water? | it decreases the surface tension of the water
🗑
|
||||
| What characteristic of water prevents water from evaporating too rapidly? | has lower vapor pressure which means that it has a wider range of temperatures
🗑
|
||||
| Liquid water forms small round beads on flat surface, why does this happen? | surface tension will hold water molecules together
🗑
|
||||
| What is the best way to determine if a mixture contains dissolved solids? | place electrodes in the water and observe if it conducts electricity
🗑
|
||||
| What atom in water is most electronegative? | oxygen
🗑
|
||||
| What are some examples of colloids? | smoke, fog, milk, and mayonnaise
🗑
|
||||
| What is the difference between a solution and a hydrate? | hydrates are crystals that contain water molecules while solutions are solutes that are dissolved in water
🗑
|
||||
| What compounds are most soluble in water? | ionic compounds(salts; Groups 1,2,3 + Groups 5,6,7,or polyatomics)
🗑
|
||||
| Interferes with hydrogen bonding between water molecules | surfactant
🗑
|
||||
| dissolving medium | solvent
🗑
|
||||
| homogeneous mixture of water and dissolved substances | aqueous solution
🗑
|
||||
| solute ions or molecules are surrounded by solvent molecules | solvation
🗑
|
||||
| compound that will conduct current in the liquid state or in aqueous solution | electrolyte
🗑
|
||||
| compound that ionizes incompletely in aqueous solution | weak electrolyte
🗑
|
||||
| mixture in which particle size averages between 1 nm and 1000 nm | colloid
🗑
|
||||
| inward force tending to minimize surface area of a liquid | surface tension
🗑
|
||||
| dissolved particle | solute
🗑
|
||||
| mixture in which particle size averages greater than 1000 nm in diameter | suspension
🗑
|
||||
| colloidal particles spread throughout a suspension | dispersed phase
🗑
|
||||
| phenomenon observed when beam of light passes through a colloid | Tyndall Effect
🗑
|
||||
| chaotic movement of colloidal particles | Brownian motion
🗑
|
||||
| colloid of a liquid in a liquid | emulsion
🗑
