Auburn University Questions with
Accurate Solutions 2025-2026 Update.
scientific notation - Answer can be written as 1.23 x 10^3 or 1.23e3. positive exponents
mean bigger than one, negative exponents mean smaller than one
atom - Answer smallest particle of an element that retains the chemical characteristics of
that element
element - Answer substance that CANNOT be separate into simpler substances by a chemical
process
compound - Answer substance composed of proportions of two or more elements
chemically bonded together. CAN be separated by chemical methods
law of definite proportions - Answer compounds always contain the same proportion of their
component elements
law of constant composition - Answer all samples of a particular compound have the same
elemental composition no matter their source
law of multiple proportions - Answer an element may combine in different ratios with
another element forming different compounds
chemical formula - Answer a notation for representing the elemental composition of a pure
substance. a ratio using the symbols of the elements. subscripts represent the relative number
of atoms of each element in the substance
matter - Answer anything that has mass and occupies space
chemistry - Answer the study of matter (its composition, structure, properties, and changes)
intensive properties - Answer independent of the amount of substance present (color, odor,
shape, boiling point)
extensive properties - Answer dependent on the amount of substance (mass, volume,
length)
,quantitative properties - Answer properties measured with a number (density, boiling point,
molar mass)
qualitative properties - Answer properties not measured with a number; usually based on an
observation (color, odor)
physical properties - Answer properties that can be measured or observed without changing
the substance (melting point, temperature, density)
chemical properties - Answer how a substance wil react. *the substance will change into a
new substance because of chemical properties (oxidation, flammability, corrosiveness)
chemical bond - Answer force that holds atoms together
molecule - Answer group of atoms with no charge
ions - Answer atoms that have a positive or negative charge
True - Answer True or False: the properties of compounds are different than the properties
of the elements that make up that compound
mixture - Answer can be separated into its components by physical means
homogenous mixture - Answer all components of the mixture of uniformly distributed;
appearance is consistent throughout the sample (also known as a solution)
heterogenous mixture - Answer composition of the mixture is not uniform; appearance may
be inconsistent
solid - Answer state of matter with a definite shape and volume
liquid - Answer state of matter with indefinite shape and definite volume
gas - Answer state of matter with indefinite shape and volume
sublimation - Answer transition from a solid to gas
, deposition - Answer transition from gas to solid
melting - Answer transition from solid to liquid
freezing - Answer transition from liquid to solid
condensation - Answer transition from gas to liquid
vaporization - Answer transition from liquid to gas
energy - Answer the capacity to do work.
work - Answer exertion of a force through a distance.
potential energy - Answer stored energy due to its composition or position
kinetic energy - Answer energy of motion. product of mass and speed.
heat - Answer form of energy that is a transfer of energy due to difference in temperature
law of conservation of energy - Answer energy is neither created nor destroyed, only
changed in form
molecular formula - Answer formula that shows what element and how many
structural formula - Answer formula that shows connection between atoms
ball and stick model - Answer "formula" that shows atoms as balls with specific colors, and
bonds are shown by sticks. this shows the angles
ionic compounds - Answer contains ions (charged particles) held together by attraction of
opposite charges.
empirical formula - Answer determined by experimentation. the smallest ratio of atoms
possible for a given substance
