HONORS CHEMISTRY PRACTICE TEST FINAL 1
EXAMPREP 2026 COMPLETE QUESTIONS AND
ANSWERS ALREADY PASSED
◉ Element.
Answer: a substance that cannot be separated or broken down into
simpler substances by chemical means; all atoms of an element have
the same atomic number
◉ Extensive properties.
Answer: depends on the size of the sample; mass, volume, length,
shape, weight
◉ Physical change.
Answer: a change of matter from one form to another without a
change in chemical properties (change of state or separation);
distilation, filtration, binding sites, decanting, chromatography,
evaporation
◉ States of matter.
Answer: solid, liquid, gas, plasma
,◉ solid.
Answer: ordered arrangement, fixed positions, can only vibrate in
place, does not fill container
◉ liquid.
Answer: close clusters of particles (disorder), free to move relative
to each other (fluid), does not fill container
◉ gas.
Answer: lots of empty space between particles (disorder), complete
freedom of movement, fills a container, constantly moving in straight
line until stopped
◉ plasma.
Answer: ionized gas (gave off electrons to form ion), has electrical
charge
◉ Chemical change.
Answer: A change in matter that produces one or more new
substances
◉ evidence of chemical change.
Answer: color change, form a gas, formation of precipitate
(cloudy/gel, insoluble solid), energy change (endo/exo)
, ◉ Mixture vs. compound.
Answer: Mixtures are physically combined and compounds are
chemically combined.
◉ Pure substance.
Answer: have a fixed composition; always homogeneous; every
sample has the same characteristic properties and composition; all
elements and compounds
◉ group properties periodic table.
Answer: valence electrons, vertical, 18, similar characteristics
◉ Periods.
Answer: Horizontal rows on the periodic table, 7, energy level
◉ Metal vs. nonmetal properties.
Answer: metal-luster, solid, malleable, good conductors, ductile
nonmetal-dull, liquid or gas or a brittle solid, poor conductors
◉ Noble gas properties.
Answer: Colorless, odorless, low reactivity, 8 valence electrons,
stable
