Activity Series
|
A list of elements in order of decreasing activity; the activity series of halogens is Fl, Cl, Br,I
|
|
|
Balanced equation
|
A chemical in which mass is conserved; each side of the equation has the same number
of atoms of each element |
|
|
Catalyst
|
A substance that increases the rate of reaction by lowering the activation-energy barrier; the catalyst is not used up in the reaction
|
|
|
Chemical Equation
|
An expression representing a chemical reaction; the formulas of the reactants (on the left) are connected by an arrow with the formulas for the products (on the rights)
|
|
|
Coefficient
|
A small whole number that appears in front of a formula in a balanced chemical equation
|
|
|
Combination Reaction
|
A chemical change in which two or more substances react to form a single new substance; also called a synthesis reaction
|
|
|
Combustion Reaction
|
A chemical change in which an element or a compound reacts with oxygen, often producing energy

|
Double-replacement reaction
|
A chemical change that involves an exchange of positive ions between two compounds
|
|
|
Net Ionic equation
|
An equation for a reaction in solution showing only those particles that are directly involved in the chemical change
|
|
|
Single-replacement Reaction
|
A chemical change in which one element replaces a second element in a compound; also called a displacement reaction
|
|
|
Skeleton Equation
|
A chemical equation that does not indicate the relative amounts of reatants and products
