Prentice Hall Chemistry Chapter 11 Vocabulary
Terms in this set (14)
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).
A chemical equation that does not indicate the relative amounts of reactants and products.
A substance that speeds up the reaction but is not used up in the reaction. It's neither a reactant nor a product so its formula is written above the arrow in a chemical equation.
Small whole numbers that are placed in front of the formulas in an equation in order to balance it.
Each side of the equation has the same number of atoms of each element and mass is covered.
A chemical change in which two or more substances react to form a single new substance.
A chemical change in which a single compound breaks down into two or more simpler products.
A chemical change in which one element replaces a second element in a compound.
Activity Series of metals
Lists metals in order of decreasing reactivity.
A chemical change involving an exchange of positive ions between two compounds.
Complete Ionic Equation
An equation that shows dissolved ionic compounds as dissociated free ions.
An ion that appears on both sides of an equation and is not directly involved in the reaction.
Net Ionic Equation
An equation for a reaction in solution that shows only those particles that are directly involved in the chemical change.
A chemical change in which an element or a compound reacts with oxygen, often producing energy in the form of heat and light.
