CHEM-120 CHAMBERLAIN FINAL
EXAM WITH CORRECT QUESTIONS
AND ANSWERS 2025
Chemistry - CORRECT-ANSWERSThe study of the properties of matter and how matter
changes
Basic Unit in Chemistry - CORRECT-ANSWERSatom
Types of Chemistry - CORRECT-ANSWERSGreen Chemistry
Sustainable Chemistry
green chemistry - CORRECT-ANSWERSuses 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-ANSWERSreplacement of mercury fluorescent light
bulbs with efficient mercury free light bulbs
Green Chemistry Solar Fuels - CORRECT-ANSWERSsunlight is abundant source of energy
plants store solar energy as chemical energy via photosynthesis
artificial photosynthesis - CORRECT-ANSWERScan 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-ANSWERSdesigned to meet the needs of the present
generation without compromising the needs of future generations
Matter - CORRECT-ANSWERSAnything that has mass and takes up space
mass - CORRECT-ANSWERSA measure of the amount of matter in an object
weight - CORRECT-ANSWERSA measure of the gravitational force exerted on the matter of an
object.
Classes of Matter - CORRECT-ANSWERSSolids, Liquids, Gas
Solid - CORRECT-ANSWERSDefinite shape and volume
vibration
ice, brick, wood,
liquid - CORRECT-ANSWERSA state of matter that has no definite shape but has a definite
volume.
move in irregular pattern
petrol, vinegar, paint, water
gas - CORRECT-ANSWERSA state of matter with no definite shape or volume
freely move continuously- far apart
helium, oxygen, carbon monoxide, hydrogen
,melting point - CORRECT-ANSWERSThe temperature at which a solid becomes a liquid
Vaporation - CORRECT-ANSWERSLiquid to gas
boiling Point - CORRECT-ANSWERStemp at which liquid escapes and becomes a gas
condensation - CORRECT-ANSWERSGas to liquid
freezing - CORRECT-ANSWERSliquid to solid
occurs at freezing point/same as melting point
Sublimation - CORRECT-ANSWERSA change directly from the solid to the gaseous state
without becoming liquid
Ex: dry ice
2 categories of matter - CORRECT-ANSWERSsubstances and mixtures
Substance - CORRECT-ANSWERSA single kind of matter that is pure and has a specific set of
properties.
Substance contains - CORRECT-ANSWERSElements and Compounds
Elements - CORRECT-ANSWERSA 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-ANSWERS2 or more elements chemically combined
, many exist as groups of atoms bonded together as molecules
Atoms - CORRECT-ANSWERSBuilding blocks of matter
smallest particle in an element
Aristotle - CORRECT-ANSWERSA Greek Philosopher,
all matter is composed of 4 elements
all matter is continuous not atomistic
WEAF- water, earth, air, water
Atomos - CORRECT-ANSWERSLecuippus/democritus
point at which matter can no longer be subdivided
Mixtures - CORRECT-ANSWERSA combination of two or more substances that are not
chemically combined
homogeneous mixture - CORRECT-ANSWERSa mixture that is uniform in composition;
components are evenly distributed and not easily distinguished
Ex: sugar and water
heterogeneous mixture - CORRECT-ANSWERSA mixture that is not uniform in composition;
components are not evenly distributed throughout the mixture
Ex: oil and water
Measurement of Matter - CORRECT-ANSWERSmass
