Gasses

TermDefinition
Dispersion forces - nonpolar molecules (Noble gasses) --> don't have a dipole - e- momentarily shift to create a temporary dipole - weakest IMF w/ the lowest boiling point
Dipole - Dipole forces - polar molecules --> have a dipole - partial negative side attracted to partial positive side of the other molecule
Hydrogen bonds - type of dipole-dipole --> same requirements - requires an H bonded to an Fl, O, or N (3 most e-negative --> most polar dipoles) - strongest IMF w/ highest boiling point
Pressure unit conversions 1 atm = 760 mmHg = 101.3 kPa
Barometer Used to measure atmospheric pressure
STP 1 atm, 0 degrees C
Dalton's Law of Partial Pressures -Partial pressure is the pressure due to an individual component in a mixture -Total pressure is the sum of the partial pressures of the individual components - P(outside) = P(inside)
Collecting gasses over water Using Dalton's law and water vapor pressure, you can find the other gas being measured

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
