Conversion of Celsius to Kelvin
|
K=C + 273.15
|
|
Mass Percent of a an element in a compound
|
Mass percent of a element = (number of atoms of that element)(atomic weight of that element)/formula weight of compound
|
|
Percent Yield
|
Perecent Yield= (Experimental Yield/Theoretical Yield) * 100
|
|
Dilution Equation
|
M1V1=M2V2
|
|
Kinetic Energy
|
Ek=(1/2)mv2
|
|
Change in Internal Energy (delta E) during a reaction
|
DeltaE= q + w
|
|
Work done by an expanding gas at constant pressure
|
W=-PdeltaV
|
|
Enthalpy Change during a reaction
|
DeltaH = deltaE + PdeltaV = qp
**Only at Constant Pressure!! |
|
Heat Gained or lost using specific heat (calorimetry eqn)
|
Q=Cs*m*deltaT
|
|
Standard Enthalpy of Reaction
|
DeltaHorxn = sum(n*deltaHoprod) - sum(m*deltaHoreac)
|
|
Constancy of speed of light
|
C= wavelength * frequency = 3 * 108m/s
|
|
Energy of a photon
|
E=hv
E=energy of a photon in joules h=Planck's constant v=frequency |
|
Matter as a wave
|
Wavelength=h/mv
h=Planck's constant v=speed of object |
