What is the general rule for density and then what is the exception of the trend when shown in water
|
The rule of density goes solid to liquid to gas
In water it goes Liquid to Solid to Gas |
|
|
What are the ABC'S of gases
|
Avogrado’s Law-PLATE
STP = 1 atm at 0 degress celcius Standard state= 1 atm at 25 degress 1 mol = 22.4 L Boyle’s Law-BAT Temp!!!! is held constant Volume is inversely proportional to Pressure Charles Law-CAP Pressure is constant Volume proportional to Temperature |
|
|
What is Dalton's Law
|
Dalton's Law states
The sum of the partial pressures equals the whole pressure |
|
|
How can you determine partial pressure
|
A mole fraction of the gas * total pressure= partial pressure of that gas
|
|
|
When is the combined gas law used
|
When the number of moles remains constant
|
|
|
How can you determine the effusion rate (rate at which gas escapes)
|
(mass1/mass2)^1/2 –rate of moving
|
|
|
What are the rules for kinetic molecular theory
|
The gases have no imf- gas molecules have few collisions and are elastic so have no IMF
They occupy no volume Also no repulsions or attractions between gas molecules |
|
|
What is present in real gases
|
They have a volume less than ideal volume- because gas molecules take up space and decrease effective volume of container
Pressure is less than ideal, has IMF forces and this reduces the collision with container |
|
|
How to approach ideality
|
Low Pressure and High Temperature
Have mono-atomic gases as opposed to diatiomic Lower molecular weight of gas are more ideal Weaker the intermolecular forces the more ideal |
