| eqn for avogadros principle | n/V=k or n/V=n/V
🗑
|

| Ideal gas law | PV=nRT
🗑
|
||||
| to solve for density using gas laws | PV/T=PV/T; V1= 22.4L, P1= 1atm, T=273.15
🗑
|

| solve molar mass of unknown gas | density at stp then x 22.4 L
🗑
|
||||
| real gases deviate from ideal gases at | high pa and low temps
🗑
|
||||
| effect of high pa on gas | condenses to liquid; the gas will occupy a larger than predicted vol
🗑
|
||||
| effect of low temps on gas | it has a smaller than expected col
🗑
|
||||
| daltons law | tot pressure = the sum of the partial pressure of each gas
🗑
|
||||
| solving an individ partial pressure | P=Pt * X
(X= mol/totmole)
🗑
|
||||
| eqn for diffusion / effusion of gases | r1/r2= (MM2/MM1)^1/2
(molar mass
heavier gas diffuse slower
🗑
|
||||
| at high altitudes/ low pressure the boiling point | increases
🗑
|
||||
| increase volume we favor | least moles
🗑
|
||||
| real gases behave ideal at | high temp and low pressire
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
