 a representation of a chemical reaction; the formulas of the reactants (on the left) are connected by an arrow with the formulas of the products (on the right). 

• chemical equation

• skeleton equation

• balanced equation

 a chemical equation that does not indicate the relative amounts of the reactants and products

• skeleton equation

• balanced equation

• complete ionic equation

a substance that speeds up the reaction but is not used up in the reaction.

Coefficients-small whole numbers that are placed in front of the formulas in an equation in order to balance it

• catalyst

• combination reaction

• Coefficients

small whole numbers that are placed in front of the formulas in an equation in order to balance it. 

• Coefficients

• catalyst

• single-replacement reaction

each side of the equation has the same number of atoms of each element and mass is conserved

• balanced equation

• complete ionic equation

• net ionic equation

a chemical change in which two or more substances react to form a single new substance

• combination reaction

• single-replacement reaction

• double-replacement reaction

 a chemical change in which a single com- pound breaks down into two or more simpler products

• decomposition reaction

• single-replacement reaction

• double-replacement reaction

a chemical change in which one ele- ment replaces a second element in a compound

• single-replacement reaction

• double-replacement reaction

• combustion reaction

 a chemical change involving an exchange of positive ions between two compounds. 

• double-replacement reaction

• combustion reaction

• combination reaction

a chemical change in which an element or a compound reacts with oxygen, often producing energy in the form of heat and light

• combustion reaction

• combination reaction

• decomposition reaction
