QuestionAnswer
Conversion for Celsius to Fahrenheit degrees in F-32*5/9
Who discovered the charge of an electron? Robert Millikan
The following data were collected when analyzing a compound used in dentistry to cement repaired teeth: 50.82% Zn; 16.04% P; 33.14% O What is the empirical formula of the compound? Converting each percentage to a mass, then dividing by the molar mass of each component gives 0.7796 mol Zn, 0.5179 mol P and 2.071 mol O or converted to small whole numbers: 3 mol:2 mol:8 mol, respectively.
Percent Yield actual over theoretical *100
Molarity M=mol/vol
solution dilution M_1V_1=M_2V_2
Gas Laws PV=nRT
Pressure, force, and area P=F/A
Charles Law V_1/T_1=V_2/T_2
Avogadro's Law V_1/n_1=V_2/n_2
Dalton's Law P_total=P_a+P_b+P_c.... with P_x=n_xRT/v
mole fraction chi_a=mole_a/mole_total
Pressure for a mole P_a=chi_a*P_total
Average Kinetic Energy 3/2RT
Kinetic Energy 1/2mass*volume^2
Internal energy Delta E=q(heat)+w(work)
Heat q=C(heat capacity)*delta T(change in temperature)
heat with mass q=mass*specific heat*delta T
work -pressure*change in volume (delta V)
Bomb Calorimeter C_cal * change temperature
Enthalpy delta H= internal energy + pressure*change in volume
heat of the reaction sum of the products - sum of the reactions
frequency frequence = speed of light/ wavelength
energy energy= planks * frequency energy= h*speed of light/ wavelength
De Broglie Relation plancks/mass*velocity
Energy of an Electron in an Orbital with Quantum Number n in a Hydrogen Atom E_n=-2.18*10^-18J(1/n^2) ...( n=1,2,3...)

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.
