Chemistry final exam

QuestionAnswer
mole 6.02214 × 10^23
Avogadro’s number 6.02214 × 10^23
stoichiometry quantitative study of reactants and products in a chemical equation
molar ratio a ratio from the two coefficients being used from a balanced a equation
gases in terms of kinetic-molecular theory state of matter which has no definite shape and no definite volume. Take shape and volume of the container they are placed in.
temperature kinetic energy of gas particles
pressure the force applied per unit area. Gas particles experience elastic collisions which mean they collide without losing energy.
Dalton’s Law of Partial Pressure P1+P2+P3+...
Boyle’s Law P1xV1=P2xV2. inverse -> pressure+volume
Charles’s Law V1/T1=V2/T2.Direct -> volume+temperature
Gay-Lussac’s Law P1/T1=P2/T2. Direct -> Pressure+temperature
Combined Gas Law P1xV1/T1=P2xV2/T2
Ideal Gas Law PV = nRT
solution a homogenous mixture of two or more substances
suspensions a heterogeneous mixture in which the solid particles are spread throughout the liquid without dissolving in it
colloids any substance consisting of particles substantially larger than atoms or ordinary molecules but too small to be visible to the unaided eye
Molarity the number of moles of solute dissolved in one liter of solution
Theoretical yield A theoretical yield is a calculated value instead of a laboratory values
conversion factor a number used to change one set of units to another, by multiplying or dividing
solute dissolved in the solvent
solvation Solute particles are surrounded by solvent particles
soluble able to be dissolved
insoluble unable to be dissolved
miscible forming a homogeneous mixture when added together.
immiscible not forming a homogeneous mixture when added together.
dilution the action of making something weaker in force, content, or value. formula V1xM1=V2xM2
compound’s percent composition (mass of element/molecular mass) x 100
Solvent able to dissolve substances
solubility the ability for something to dissolve in something and form a solution

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.
