Chemistry 1120 Bennett Exam One Review – Full Chemistry Exam
Preparation Guide
What is Chemistry? - ANS ✔✔the study of the composition, structure, properties, and reactions
of matter
Matter - ANS ✔✔anything that has mass and occupies space
Sunlight is not matter
Physical Properties - ANS ✔✔physical properties are observed or measure w/o changing its
identity
ex: shape, taste, size, density, color, mp, bp
Chemical Properties - ANS ✔✔describe the way a substance may change or react to form other
substances
ex: flammability
Physical Change - ANS ✔✔substance retains identity
ex: freezing, melting, dissolving
Chemical Change - ANS ✔✔some new substance is produced
ex: burning, corrodes, rusts
, What three forms does matter exist? - ANS ✔✔Gas, Liquids, Solids
Solid - ANS ✔✔they have:
-a definite shape and volume (as long as the T & P stay constant)
-particles close together
-particles move slowly
Liquids - ANS ✔✔they have:
-an indefinite shape; it assumes the container
-a definite volume
-particles are close together, but mobile
Gas - ANS ✔✔they have:
-an indefinite shape
-an indefinite volume
-conform the shape of the container, but it also expands to fill container
-particles are fast moving and far apart
What volumes do not change in a different container? - ANS ✔✔Solids and Liquids
The Matter Tree - ANS ✔✔
Pure Substances - ANS ✔✔matter with a specific composition, its only made up of component
Pure substances can be classified by what two things? - ANS ✔✔An element and a compound
