What forumlas am i supposed to remember for tomorrow?

[callum_250]

Just wondering what formulas i should attempt to remember tomorrow so i can atleast achieve a pass in chem.

General equations:

n = m/Mr
c = n/V
pV = nRT

pH equations

pH = -log[H+]
[H+] = 10^-pH
[H+][OH-]= 10^-14 (at 25 degrees)

Heat of reactions

E = mcT  (m is mass of water, c is specific heat capacity, T is change in temp)
Delta H = E/n kj mol-1
            = E/g kj g-1
CF = VIt / delta T
E = delta H x mole

Faradays

n(e-) x F = It
Q = It
Q = n(e-) x F
E = VIt

[wth..]

Also, E=VQ.

[arthurk]

wonder if theyll use VQ again since they used it a while back
maybe this time it will be like E = Pt

[d0minicz]

wats E=pt?

[kamil9876]

power equals energy over time

[emkate]

power equals energy over time

we're meant to know that?

[simpak]

Bullshit we need to know that, STOP FREAKING ME OUT GUYS.

OH WAIT, do we need to know the surface area equation that relates mass and volume and surface area or something along those lines?
