1 Calorie (Cal-uppercase) in cal-lowercase
1 Cal/Calorie = 1000 cal
1 calorie (cal) in Joules
1 cal/calorie = 4.184 J
1 electron-volt (eV) in joules
1 electron-volt (eV) = 1.602 * 10^-19 J
1L in ounces
1L = 33.8 ounces (oz)
1 pound (lb) in N
1 pound (lb) = 4.45 N
1 atomic mass unit (amu) in kg
1 atomic mass unit (amu) = 1.6 * 10^-27 kg
Sound level formula
20 dB = 10 log (I / Io)
2 = log (I / Io)
10^2 = I / Io
Reference Sound Intensity (Io) = 10-12 W/m²
exponential decay
arrhenius eq for activation energy
gibbs free energy delta G in e
k=e^(-deltaGstandard/RT)
ph in [concentration]
Henderson Hasselbach
gibbs free and Ecell
Q and Ecell
electrodeposition
the number of moles of element being deposited on a plate
delta G standard vs. non-standard
If E° cell is positive, In Keq is positive. This means that Key must be greater than one and that the equilibrium lies to the right (products are favored).
delta G, enthaply entropy
density of water
ρwater = 10^3 kg/m^3
