Charle's Law + Equation the volume of a gas is directly proportional to it's absolute temp when pressure and mols of gas are constant (V1/T1 = V2/T2)
Boyle's Law + Equation The pressure of a given mass of an ideal gas is inversely proportional to it's volume when the pressure remains constant (P1V1 = P2V2)
Percent Mass equation % mass = part/whole x 100
Define Atom smallest unit of an element that is still an element
Define Molecule multiple atoms bonded together that act as a unit (same element)
Define Compound atoms of 2 or more different elements that are bonded together
Define Mixtures not pure substance
Explain Homogeneous mixture separate parts of the mixture are not visible
Explain Heterogeneous mixture separate parts of the mixture are visible
Define pure substance constant uniform composition
Avagadro's number 6.022e23
Universal gas constant 0.08206
Empirical formula: Lowest whole number ratio
Molecular formula: actual composition of a compound
How to find empirical formula? convert from grams to moles, divide by lowest mole number, and multiply until getting whole numbers
Components of KINETIC MOLECULAR THEORY 1. gas particles constant random motion 2. pressure is bcuz of particle collisions within container walls 3. average kinetic energy of the gas depends on the temperature 4. particle volume is negligable 5. gas particles = no attraction nor repulsion
Variables of KINETIC MOLECULAR THEORY P = pressure V = Volume in L n = moles R = Universal gas constant (0.08206) T = Temperature in Kelvin

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.
