General Chemistry 1 UPDATED ACTUAL
Exam Questions and CORRECT Answers
States of Matter - CORRECT ANSWER✔✔- solid, liquid, gas
Scientific Method: Qualitative - CORRECT ANSWER✔✔- observations, descriptions
Scientific Method: Quantitative - CORRECT ANSWER✔✔- values, measured
Scientific Method: Hypothesis - CORRECT ANSWER✔✔- educated guess
if/then
testable question
Scientific Method: Experiment - CORRECT ANSWER✔✔- to test hypothesis
Scientific Method: results - CORRECT ANSWER✔✔- data
literature
Scientific Method: law - CORRECT ANSWER✔✔- "facts"
Ex: Charles Law, Murphy's Law, Newton's Law, etc
Scientific Method: theory - CORRECT ANSWER✔✔- understanding
use to explain + predict
Volume - CORRECT ANSWER✔✔- space occupied by something
physical property/change - CORRECT ANSWER✔✔- may change state or phase but not the
identity
ex: temperature
,Chemical property/change - CORRECT ANSWER✔✔- change identity of the chemical
Solution components: Solvent - CORRECT ANSWER✔✔- water
if homogenous, mixture takes on place of solvent
Solution components: solute - CORRECT ANSWER✔✔- dissolves in solvent
can be many
ex: salt
Solution components: Aqueous phase - CORRECT ANSWER✔✔- mixture with water as a
solvent
H2O break down - CORRECT ANSWER✔✔- H:O
1:8 (by mass)
O atoms are larger than H atoms
H atoms are lighter than O atoms
extensive properties - CORRECT ANSWER✔✔- chemical based on amounts, measured
mass
volume
intensive properties - CORRECT ANSWER✔✔- tabulated, doesn't depend on amounts
Energy Units - CORRECT ANSWER✔✔- Joules (J)
1 J = 1 (kg)(m^2)/(s^2)
mass - CORRECT ANSWER✔✔- measure by a balance
grams (g)
Energy (Ek: Kinetic energy) - CORRECT ANSWER✔✔- Ek: (1/2)(m)(v^2)
, measured in J
m = mass
v = volume
scientific notation - CORRECT ANSWER✔✔- convert to sci notion from standard notation
the prefix = 10^#
volume (v) - cubed - CORRECT ANSWER✔✔- Vcube = (length)(width)(height)
1cm^3 = 1 mL
density - CORRECT ANSWER✔✔- mass of a substance for a given volume of that
substance
d = m/v
unit: g/(cm^3) or g/mL
Temperature - CORRECT ANSWER✔✔- relative tendency of heat to escape from an object
Temperature: Celsius (C) - CORRECT ANSWER✔✔- 0 C = freezing point
100 C = boiling point
Temperature: Kelvin (K) - CORRECT ANSWER✔✔- no particle motion
degree difference is the same for C + K
Temperature: Fahrenheit (F) - CORRECT ANSWER✔✔- salt water
freezing + boiling
Measurements - CORRECT ANSWER✔✔- report all certain digits and one uncertain digit
