CHEM 1211 GEORGIA SOUTHERN TEST 1 QUESTIONS ANSWERED CORRECTLY LATEST UPDATE 2026
Matter - Answers anything that has mass ans takes up space.
Atoms - Answers building blocks of matter, and they are the smallest form of matter other than
subatomic particles.
Element - Answers all made up of the same kind of atom for one element.
Molecule - Answers two or more atoms held together by covalent bonds, in specific shapes.
Compound - Answers made up of two or more different elements that are combined.
3 forms of matter - Answers solid, liquid, gas
Gas - Answers no fixed volume, easy to compress
Liquid - Answers distinct volume, compressible but not as much as gas
Solid - Answers fixed shape and volume, not compressible.
Pure substance - Answers usually referred to as substance, has distinct properties and a composition
that does not vary from sample to sample. 2 types of pure substances: elements, and compounds.
2 forms of pure substance - Answers Element: a substance that cannot be decomposed to simpler
substances. EX: anything on the periodic table of elements.
Compound: a substance which can be decomposed into simpler substances. EX: H2O, (it can be
broken down)
Mixture - Answers Exhibit the properties of the substances that make them up. 2 types:
Heterogenous and Homogenous.
2 types of mixtures - Answers homogeneous: also known as solution, their compositions do not vary
throughout a sample. EX: coffee, or smoothie, you can't see the milk and coffee and sugar separated.
heterogeneous: their compositions vary throughout a sample. EX: Pizza, you can pick the pepperoni
from the cheese or sauce, another example would be granite countertop because you can see the
different types of rocks.
Heterogeneous - Answers their compositions vary throughout a sample. EX: Pizza, you can pick the
pepperoni from the cheese or sauce, another example would be granite countertop because you can
see the different types of rocks.
Homogeneous - Answers also known as solution, their compositions do not vary throughout a
sample. EX: coffee, or smoothie, you can't see the milk and coffee and sugar separated.
Physical properties of Matter - Answers can be observed withOUT changing a substance into another
substance. EX: boiling point, density, mass, volume
Chemical properties of Matter - Answers Can only be observed when a substance is changed into
another substance. EX: flammability, corrosiveness, reactivity with acid.
2 types of properties of matter - Answers intensive and extensive and they are interchangeable
within chemical and physical properties of matter.
Intensive property - Answers independent of the amount of substance present. EX: density, boiling
point, color
Extensive property - Answers a property that depends on the amount of matter in a sample. Ex: mass,
volume, or energy.
Physical change - Answers A change in a substance that does not involve a change in the identity of
the substance. EX: changes of state, temperature and volume.
Chemical change - Answers A change in matter that produces one or more new substances. EX:
combustion, oxidation, and decomposition.
Mass - Answers SI Base Unit: Kilogram or kg. Metric uses Gram but we use SI. Measures the amount
of material in an object.
Length - Answers SI Base Unit: Meter or m. It measures distance.
Temperature - Answers SI Base Unit: Kelvin or K
Time - Answers SI Base Unit: second, s or sec.
Amount of substance - Answers SI Base Unit: mole or mol.
Volume - Answers most commonly used units are liter (L) or milliliter (ml). A liter is a cube 1 (dm) long
on each side. And a milliliter is a cube 1 (cm) long on each side.
Exact numbers - Answers counted or given by definition. EX: 12 eggs in a dozen, or 1000g in a
kilogram.
Inexact numbers - Answers or Measured Numbers, depend on how they were determined. scientific
instruments have limitations.
