So I was thinking to myself........which is extremely scary by the way.........that I (and I am sure that there are more out here) can never seem to remember all the gchem formulas and figured it would be a nice idea to start one.

I did search the forums but alas none existed that I could find so I shall start (if there is a constant value involved please list it):

STP= (1 atm, T=273K)

PV=nRT (ideal gas law) (n=.0821)(under STP see above for T and P) (R=number of moles)

T= -k*i*m (freezing point) (affect bp/mp)(k= solvent constant)

T= k*i*m (boiling point) (see above)

G= H-T*S (Gibbs free energy) (G= -2.3RT log Keq)

You got the R and the n mixed up buddy... R= 0.0821 and n is no. of moles (I'm sure you knew that!!! But just to make sure you knew it..)

T= -k*i*m (freezing point) (affect bp/mp)(k= solvent constant)

T= k*i*m (boiling point) (see above)

G= H-T*S (Gibbs free energy) (G= -2.3RT log Keq)

OH SNAP!! Thanks alot bro. It is late for me and I guess my hand eye coordination is lacking........not to mention brain function😴

That's cool.. It happens..🙂
And, its 'Sista'... No bro here !!😛

Hey now. Didn't realize we had a neubian goddess on our hands. Sorry for the stereotypical response.😎

Also for the ideal gas law pv=nRT you can rearrange it to use it for density and molar mass. So then you have p(MM)=DRT.

G= H-T*S (Gibbs free energy) (G= -2.3RT log Keq)

deltaG = n*F*E(cell)
nF = it (i= current in amps (C/s); t = time)
Q=m*c*deltaT (Q = enthalpy; c = specific heat capacity)
O = MRT (O = osmotic pressure; M = molarity; R = some constant?? T = temp)
pH = pKa + log[HB/HA] (Henderson Hasselbach for buffers)

T= -k*i*m (freezing point) (affect bp/mp)(k= solvent constant)

T= k*i*m (boiling point) (see above)

can som1 explain what these are? what is "affect bp/mp"?
