activation energy
The energy that must be overcome for a chemical reaction to occur.
Electrical forces linking atoms.
Substances that increase the rate of a chemical reaction without being changed themselves at the end of the reaction.
chemical equation
A way to describe a chemical reaction using chemical formulas and other symbols.
chemical reaction
The change that occurs when two or more substances interact to form new substances.
law of conservation of mass
In a chemical reaction, matter isn't created or destroyed.
The substances produced in a chemical reaction.
The chemical substances present at the start of a chemical reaction.
aqueous solution
A solution of particles dissolved in water.
combination reaction
A chemical reaction where two or more reactants form one product.
combustion reaction
A chemical reaction in which energy is produced in the form of heat and light.
decomposition reaction
When a substance is broken down into two or more simpler substances in a chemical reaction.
double-displacement reaction
When the positive ion of one compound replaces the positive ion of the other compound to form two new compounds during a chemical reaction.
Subatomic particles that carry a negative charge.
Incapable of being dissolved.
An atom that has either gained or lost electrons and so has an electrical charge.
ionic compound
A compound, usually formed from a metal and a nonmetal atom, that results from ionic bonding.

To lessen the concentration of a solution by adding more water.
A process in which an ionic compound separates into its positive and negative ions.
An organic compound that changes color when exposed to an acid or a base.
An atom or group of atoms that has either gained or lost electrons and so has an electrical charge.
litmus paper
An indicator that shows whether a solution is acidic or basic.
neutral solution
A solution that's neither acidic nor basic.
neutralization reaction
The reaction of an acid with a base in a water solution.
A measure of how acidic or basic a solution is.
strength (of an acid or a base)
The degree to which an acid or base is dissolved in a solution.
