CHM 113 FINAL MIAMI QUESTIONS &
ANSWERS 100% CORRECT
Intensive Property - ANSWERDoes not depend on the amount of the substance:
density, color, temp, melting/boiling point, solubility in water at room temp,
conductivity, taste/odor, state at room temp, malleability.
Extensive property - ANSWERDepends on how much matter you have (amount of
matter), ex: mass, volume, shape
Physical property - ANSWERproperties that can be observed without changing the
chemical composition of the substance (color, odor, temperature, density, mp, bp)
Density - ANSWERmass/volume
Specific gravity - ANSWERThe ratio of the density of a substance to the density of
water (density of water = 1 gm / cm^3)
What is used to clean up acid spills - ANSWERSodium bicarbonate
Conductivity titration graph - ANSWERV shaped graph, minimum value is the
equivalence point
Endothermic - ANSWER(of a chemical reaction or compound) occurring or formed
with absorption of heat
Exothermic - ANSWERChemical Reaction in which energy is primarily given off in
the form of heat
What separation methods did you use in the labs we have done? -
ANSWERfiltration, distillation
Percent recovery - ANSWER% recovery = weight of pure substance / weight of
crude substance * 100
What makes industrial production of adipic acid bad? - ANSWERIt produces Nitrous
oxide (N2O) a greenhouse gas
How to do 1:1 titrations and how to find the concentration of either the titrant or the
solution - ANSWERM1V1 = M2V2
M = molarity
V = Volume
Gravimetric analysis - ANSWERGravimetric determination involves conducting a
reaction such that a solid precipitate of a certain compound will form. Once formed,
the precipitate is weighed and its concentration in the original solution can be
determined. There are five distinct requirements for this process to be effective:
