Chapter 10 Flashcards
An expression representing a chemical reaction
Chemical equation
A chemical equation that does not indicate the relative amounts of reactants and products
Skeleton equation
A substance that increases the rate of reaction by lowering the activation energy barrier
Catalyst
A small whole number that appears in front of a formula in a balanced chemical reaction
Coefficient
A chemical equation in which mass is preserved; each side of the equation has the same number of atoms of each element
Balanced equation
A chemical change in which two or more substances react to form a single new substance
Combination reaction
A chemical change in which a single compound is broken down into two or more simpler products
Decomposition reaction
A chemical change in which one element replaces a second element in a compound
Single-replacement reaction
A list of elements in order of decreasing activity; the activity of halogens is F, Cl, Br, I.
Activity series
A chemical change that involves an exchange of positive ions between two compounds
Double-replacement 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
An equation that shows dissolved ionic compounds as dissociated free ions
Complete ionic equation
An ion that is not directly involved in a chemical reaction
Spectator ion
An equation for a reaction in solution showing only those particles that are directly involved in the chemical change
Net ionic equation
