List of elements in order of decreasing activity

Activity series

Chemical equation where mass in converted, each side of equation has same number of atoms for each element

Balanced equation

Substance that increase rate of reaction by lowering the activation-energy barrier not used up in the reaction

Catalyst

Represents chemical reaction

Chemical equation

A whole number in front of a chemical compound in a balanced chemical equation

Coefficients

Chemical change where 2 or more substances react and form a single new substance

Combination reaction

Chemical change where an element or compound reacts with oxygen and produces energy in form of light and heat

Combustion reaction

Shows dissolved ionic compounds as dissociated free coins

Complete ionic equation

Where single compound is broken down into 2 or more simpler products

Decomposition reaction

For reaction in solution showing only those particles directly involved in the chemical equation

Net ionic equation

1 element replaces second element in a compound

Single-replacement reaction

This does not indicate the relative amounts of reactants or products

Skeleton equation

Not directly in chemical reaction, the ion doesn't change oxidation number or composition during reaction

Spectator ion
