Rf value correct answers Distance travelled by substance / distance travelled by solvent

Thin lens equation correct answers 1/f = 1/O + 1/I

Ohm's law correct answers V=IR
Volts

Index of refraction correct answers n=c/v

Energy of a photon correct answers E=hf
Joules

Work correct answers W = force x distance
Joules

Ideal Gas Law Equation and assumptions correct answers PV=nRT
Intermolecular forces are negligible
Individual molecular volume is negligible
STP conditions

Magnification correct answers m = -i/o

Molarity correct answers moles of solute/liters of solution

Power (units) correct answers Watts
J/s
kg*m^2/S^3

Joules (units) correct answers N*m
kg*m^2/S^2

Newton (units) correct answers kg*m/s^2

Standard electromotive force correct answers The difference potential between two half-cells.
Ecell = Ecathode - Eanode

Gibbs free energy correct answers The energy in a system that can be used to drive chemical
reactions.
ΔG = ΔH - TΔS
Goldfish are Horrible without Tartar Sauce

, Aldol condensation correct answers A reaction in which an aldehyde or ketone acts as both the
electrophile and nucleophile, resulting in the formation of a carbon-carbon bond in a new
molecule.

Condensation reaction correct answers A reaction that combines two molecules into one, with
the loss of a small molecule.

SN1 reactions correct answers - Two steps: leaving group leaves, forming a carbocation that then
reacts with a nucleophile.
- Tertiary and secondary preferred over primary
- Racemic mixture
- Depends on the concentration of substrate
- Polar protic

SN2 reactions correct answers - Concerted single step where nucleophile attacks as the leaving
group starts to leave.
- Primary and secondary preferred over tertiary
- Changed in configuration
Depends on the concentration of both substrate and nucleophile
- Polar aprotic

Thermodynamic product correct answers favors energetically stable products even if they require
a higher activation energy and more time to produce.

Kinetic product correct answers favors products that form more quickly; these products will
often be less energetically stable but are formed faster due to lower activation energies.

Charge stored capacitor correct answers Q = CV
Coulombs = Farad*Volts

Energy stored correct answers U = 1/2CV^2
Joules

Boiling point correct answers Measures the strength of intermolecular forces that hold molecules
together.

UV-visible absorption correct answers Based on ground state electron excitation via the
absorption of light

Mass Spectroscopy correct answers Used for the identification of a compound via fragmentation
and analysis of its mass-to-charge ratio.

Thermodynamic stability correct answers Compound is determined by the intramolecular forces.

Henderson-Hasselbalch equation correct answers pH = pKa + log [A-]/[HA]
