List of equations needed to know?

[masonnnn]

I think i know all the equations, yet i did struggle slightly before because i couldn't remember one to do with enthalpy= energy over mol...
any considerate, good ol' champion want to do a list of equations that are necessary? so i can see if i...know them all? would be very much appreciated.

Posting cause I want to be notified when that blissful soul enlightens us with those precious equations.

[menashiiii]

n = m x M

[Martoman]

E = VQ

[menashiiii]

Q=it
Q=n(e-)xF

[JinXi]

PV= nRT

or is that unit 3

[Studyinghard]

E = VIT , YES I KNOW ITS PHYSICS BUT REMEMBER THAT SHIT. it can help to get to an answer quicker.

CF = E / ΔT
E = mcΔT
E = VIt
Q = It
and consequently E = VQ
Q = n(e-) x F
F = Charge on one electron x Avogandro's constant (values in data booklet)

Ka = K[H2O]
Kw = K[H2O]^2
Kw = [H3O+][OH-] = 10^-14 at 25ºC

pH = -log10[H3O+] (and the transposed equivalent)
[OH-] = 10^-14 / [H3O+]


C1V1 = C2V2 (perhaps)
n = m/Mr
n = Cv
n = N/NA, N = no. particles, NA = avogandro's constant
PV = nRT

* Not sure about the bolded equation. Do we take the negative? as Charge on one electron = -1.60 x 10^-19, consequently F = -96320

I remember that as Education = Victorian Institute of Teaching
In case that helps anyone

....?
or just flip it around.
VIT = E

VITE, done and done.

Specific heat capacity: Energy required (J)) = 4.184 x (mass in grams) x (Δt)
C.F. = (V.I.t) / (Δt)
Energy change of reaction = (C.F.)( Δt)
Q = It  Q= amount of charge ( C)
 I = current ( A) and t = time (s)
Q= n(e-) x F  where F = faradays const 96500
Change in energy = H (products) – H (reactants)

K = [products]/[reactants]
pH = -log10 [H+]
[H+] = 10 ^ -ph
[OH-]x[H+] = 10^-14 M^2
[H+] = (10^-14)/[H-]
Ka = K[H2O]
% hydrolosis = ([conjugate of original acid]/[original acid]) x100

A few other random ones ive seen:
E = V.I.T.
E = VQ
Change in enthalphy = E (bond breaking) – E (bond making)

also D = m/V is quite useful at times

[masonnnn]

niiicely done!!
exactly what i needed, going to print this and just look over it to make sure i remember them all haha.

also D = m/V is quite useful at times

following on from this volume=area x depth can be useful for electroplating

[cameron_15]

N = V/Vm

Mole = Volume (Litres)/Molar Volume (STP or SLC, look it up in the data book!)
