with Accurate Answers 100%.
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]
