1. STP
• ideal conditions
• Temp of OC (273K), Pressure of 1atm
• 1mole occupies a volume of 22.4L
2. Charle's Law
V2/V1 = T2/T1
3. Boyle's Law
P1V1/T1 = P2V2/T2
4. Kinetic energy of gas
KE = 3/2 nRT
5. Bernoulli's fluids equation
• A1v1 = A2v2
• (area) (velocity)
6. Normality to molarity
• monoprotic (ie HCl) is equal
• diprotic (ie H2SO4), 1N = .5M
7. Tesla units
1T = 1 N * sec/m * C
8. Volt units
1V = 1 J/C
9. Buoyancy force
• Fb = density(of FLUID) * volume * gravity
• Fb = pvg
10. Rate Law
• Need to know the slow step (rate determining step)
• aA + bB --> dD
• rate = K[A][B]
11. Gibbs free energy equation
^G = ^H - T^S
12. enthalpy
• measures heat of reaction (^H)
• this is measured by bond dissociation energy, energy required to break a bond
• ie: ^H value
13. 1st law of thermodynamics
• ^E (change in internal energy) = Q (heat added TO system) - W (work done BY system)
• ^E = Q (to system) - W (by system)
14. magnification
• m= - i/o
• if m is negative, image INVERTED
• if m is greater than 1, image is farther than object
15. focal length image and object equation
1/f = 1/i + 1/o
16. SN1 vs SN2
• SN1: rxn w/multiple steps & intermediates. produces RACEMIX mixtures. rxn accelerated by PROTIC, Polar solvents
• SN2: rxn proceeds with 1 step. accelerated by polar, APROTIC solvents
17. chiral molecule characteristic
rotates plane polarized light
18. alcohol + heated with ACID
double bond form and OH removed, so -ene formed
19. Hemoglobin affinity with fetus vs human
fetal Hb affinity is increased: Shift LEFT on curve
20. higher metabolism animals vs human hemoglobin
animals Hb affinity lower: Shift RIGHT on curve
21. acidic conditions Hemoglobin affinity vs normal
• Shift RIGHT on curve
• Down Right Bohr!
22. Ortho Meta Para groups
• Ortho & Para directing:
• -NH2
• -OH
• -NHCOR
• -OR
• -alkyl
• -aryl
• halogens
• META directing:
• N+(CH3)
• NO2
• CF3
• CN
• SO3H
• CHO
• COR
• COOH
• COOR
• CONH2
23. Thin Layer Chromotography (TLC)
utilizes a silica gel that is placed in beaker with eluant and through CAPILLARY action, liquid drawn UP the gel with the mixture
24. gel filtration
• separates based on SIZE
• small proteins go through pores in column and run slower vs the large proteins which run FAST thru
25. Hardy Weinberg Equation
• p + q = 1
• p^2 + 2pq + q^2 = 1
• (AA) + (Aa) + (aa) frequencies
