1

P1V1 formula

P1V1/n1T1 = P2V2/n2T2

2

m/v = x = y

m/v = d = PM/RT

3

alternate ideal gas using m/M

PV = mRT/M

4

PA (partial pressure A)

PA = XA * Ptot

5

Rate A/Rate B

√MB/MA

6

real gas law

(P + n^2a/V^2)(V - nb) = nRT

7

ΔE = hv =... (ie photoelectric)

hc/λ

8

de Broglie wavelength formula

λ = h/mu

9

Heisenberg uncertainty formula

Δx*mΔu ≧ h/4Π

10

possible values for:
n
ml
l

n: any positive integer
l: 0-(n-1)
ml: (for each value of l): -l - +l

11

BONUS CARD- # possible orbitals shortcut formula

n^2

12

fractional bond order formula

#shared e- pairs/#bonds

13

q or ΔH =

q = nCΔT (C is heat capacity)

14

Clausius equation

lnP = -ΔHvap/R(1/T) + C (C is constant)

15

Clausius equation for 2 vapour pressures @ 2 temperatures

lnP2/P1 = -ΔHvap/R(1/T2 - 1/T1)

16

formula for A for all 3 cubic units

simple- A = 2r
body centred- A = 4r/√3
face centred- A = (√8)r

17

volume/mol (cubes) =

cm^3/mol * packing efficiency
