CHEM 120 CHAMBERLAIN FINAL Exam Prep Material
Newest 2025/2026 Complete Questions And Correct
Answers (Verified Answers)|Brand New Version!
hemistry - CORRECT ANSWER-The study of the properties of matter and how
matter changes
Basic Unit in Chemistry - CORRECT ANSWER-atom
Types of Chemistry - CORRECT ANSWER-Green Chemistry
Sustainable Chemistry
green chemistry - CORRECT ANSWER-uses materials and processes that are
intended to prevent or reduce pollution at its source
replacing rare hazardous with more abundant less hazardous
Example of green chemistry - CORRECT ANSWER-replacement of mercury
fluorescent light bulbs with efficient mercury free light bulbs
,Green Chemistry Solar Fuels - CORRECT ANSWER-sunlight is abundant
source of energy
plants store solar energy as chemical energy via photosynthesis
artificial photosynthesis - CORRECT ANSWER-can be used to generate
hydrogen fuel
H fuel can then be reacted with O to produce heat and electricity
water---->hydrogen + oxygen
sustainable chemistry - CORRECT ANSWER-designed to meet the needs of
the present generation without compromising the needs of future generations
Matter - CORRECT ANSWER-Anything that has mass and takes up space
mass - CORRECT ANSWER-A measure of the amount of matter in an object
weight - CORRECT ANSWER-A measure of the gravitational force exerted on
the matter of an object.
Classes of Matter - CORRECT ANSWER-Solids, Liquids, Gas
Solid - CORRECT ANSWER-Definite shape and volume
vibration
,ice, brick, wood,
liquid - CORRECT ANSWER-A state of matter that has no definite shape but
has a definite volume.
move in irregular pattern
petrol, vinegar, paint, water
gas - CORRECT ANSWER-A state of matter with no definite shape or volume
freely move continuously- far apart
helium, oxygen, carbon monoxide, hydrogen
melting point - CORRECT ANSWER-The temperature at which a solid
becomes a liquid
Vaporation - CORRECT ANSWER-Liquid to gas
boiling Point - CORRECT ANSWER-temp at which liquid escapes and becomes
a gas
condensation - CORRECT ANSWER-Gas to liquid
freezing - CORRECT ANSWER-liquid to solid
occurs at freezing point/same as melting point
, Sublimation - CORRECT ANSWER-A change directly from the solid to the
gaseous state without becoming liquid
Ex: dry ice
2 categories of matter - CORRECT ANSWER-substances and mixtures
Substance - CORRECT ANSWER-A single kind of matter that is pure and has a
specific set of properties.
Substance contains - CORRECT ANSWER-Elements and Compounds
Elements - CORRECT ANSWER-A molecule composed of one kind of atom;
cannot be broken into simpler units by chemical reactions.
represented by chemical groups:
Cl, H, Mg
Compounds - CORRECT ANSWER-2 or more elements chemically combined
many exist as groups of atoms bonded together as molecules
Atoms - CORRECT ANSWER-Building blocks of matter
smallest particle in an element
