require scholars to pull together a number of science ideas in order to explain.

dissolved substances; in equations this means that the substance denoted by the
chemical formula is dissolved in a water solvent.

Atomic Number (Z) - CORRECT ANSWERS-The number of protons in the nucleus of
the atom. This determines the identity of the element of the atom.

more substances or particles toward each other.

mole of a substance with an experimentally determined value of approximately 6.02 x
1023 particles per mole.
Balance (Lab Instrument) - CORRECT ANSWERS-A lab instrument that measures the
mass.
Balanced Equation - CORRECT ANSWERS-A chemical equation in which the same
number of each type of atom is present on both the reactant and product sides.
,Balancing - CORRECT ANSWERS-The mathematical routine, which is necessary to
adhere to the law of conservation of mass, for finding the coefficients that allow the
number of atoms of each element to be the same on both sides of the yield arrow in a
chemical equation.

that hold atoms together in compounds.
Cation - CORRECT ANSWERS-Positively charged ion.

0° and boils at 100° under standard conditions.
Chemical Formula - CORRECT ANSWERS-A symbolic representation of a chemical
compound or molecule that shows the types and numbers of atoms in the compound.
Chemical Reaction (aka Chemical Change) - CORRECT ANSWERS-A process by
which one or more substances convert to one or more different substances; a change
that alters the composition of one or more chemical species through breaking and
forming bonds.

equation.
Claim - CORRECT ANSWERS-A statement made as an explanation of data collected
and analyzed or as an answer to a question.

object, usually another particle or the wall of its container, resulting in a transfer of
energy and momentum.
Compound - CORRECT ANSWERS-A pure substance composed of identical particles
containing atoms from more than one elemens held together by bonds that can only be
separated or changed by chemical reactions.
Concentrate (verb) - CORRECT ANSWERS-Increasing the amount of dissolved solute
per liter of solution.

conduct electricity.
Conductor - CORRECT ANSWERS-The materials or substances which allow electricity
to flow through them.
Control Variable (aka Constant) - CORRECT ANSWERS-Anything that is held constant
or limited in an investigation to minimize risk of error in the results.
Conversion Factor - CORRECT ANSWERS-A ratio of equivalent measurements; mainly
used in dimensional analysis and stoichiometry.
Coulomb's Law - CORRECT ANSWERS-Like charges repel; opposite charges attract.
The force is proportional to the magnitude of the charges and inversely proportional to
the square of the distance between them.
Covalent Bond - CORRECT ANSWERS-A bond that involves two highly
electronegativity atoms, usually nonmetals, sharing electrons in a distinctive location in
such a way that all atoms in the particle achieve a stable octet.
Density - CORRECT ANSWERS-Mass per unit of volume of a substance; how much
matter is in a given amount of space.
Dependent Variable - CORRECT ANSWERS-The variable being tested and measured
in an experiment, and is 'dependent' on the independent variable.
Dilute (verb) - CORRECT ANSWERS-Decreasing the amount of dissolved solute per
liter of solution.
Diluted (adjective) - CORRECT ANSWERS-Used in comparison to other solution(s),
lower ratio of dissolved solute per liter of solution that other solution(s).
Dilution - CORRECT ANSWERS-The addition of solvent, which decreases the
concentration of the solute in the solution.
Dimensional Analysis (aka Factor-Label Method) - CORRECT ANSWERS-An orderly
problem-solving process that establishes relationships between different units of
measurement through multiplying measured values by one or more known conversion
factor(s); the mathematical conversion between an amount in one unit to the
, corresponding amount in a desired unit through multiplying by one or more conversion
factors.
Dipole Moment - CORRECT ANSWERS-A measurement of the separation of positive
and negative charges in a bond or molecule.

same amount.
Dissociation - CORRECT ANSWERS-The breaking apart of an ionic compound into its
simpler constituents that are usually capable of recombining under other conditions.

process where a compound breaks down into its constituent ions when dissolved in a
solvent.

atom that has negligible mass and a negative charge equal and opposite to the proton.
Electronegativity - CORRECT ANSWERS-A measure of an atom's ability to attract
shared electrons; how strongly a nucleus attracts the electrons of another atom.
Element - CORRECT ANSWERS-Substance that is composed of a single type of atom;
a substance that cannot be decomposed by a chemical change; determined by the
number of protons in the atom.
