Balanced equation
Chemical equation where mass in converted, each side of equation has same number of atoms for
each element
Chemical equation
Represents chemical reaction
Net ionic equation
For reaction in solution showing only those particles directly involved in the chemical
equation
Activity series
List of elements in order of decreasing activity
Decomposition reaction
Where single compound is broken down into 2 or more simpler products
Catalyst
Substance that increase rate of reaction by lowering the activation-energy barrier not used
up in the reaction
Skeleton equation
This does not indicate the relative amounts of reactants or products
Coefficients
A whole number in front of a chemical compound in a balanced chemical equation
Combustion reaction
Chemical change where an element or compound reacts with oxygen and produces energy in form of
light and heat
Complete ionic equation
Shows dissolved ionic compounds as dissociated free coins
Spectator ion
Not directly in chemical reaction, the ion doesn't change oxidation number or composition
during reaction
Combination reaction
Chemical change where 2 or more substances react and form a single new substance
Single-replacement reaction
1 element replaces second element in a compound
