Chapter 11 Vocab Flashcards
activity series
lists metals in order of decreasing reactivity
balanced equation
each side of the equation has the same number of atoms of each elements and mass is conserved
catalyst
a substance that speeds up the reaction but is not used up in the reaction
chemical equation
a representation of a chemical reaction
coefficients
small whole numbers that are placed in front of the formulas in order to balance it
combination reaction
a chemical change in which two or more substances react to form a single new substance
combustion reaction
a chemical change in which an element or a compound reacts with oxygen, often producing heat or light
complete ionic equation
an equation that shows dissolved ionic compounds as dissociated free ions
decomposition reaction
a chemical change in which a single compound breaks down into two or more simpler products
double-replacement reaction
a chemical change involving an exchange of positive ions between two compounds
net ionic equation
an equation for a reaction in solution that shows only those particles that are directly involved in the chemical change
single-replacement reaction
a chemical change in which one element replaces a second element in a compound
skeleton equation
a chemical equation that does not indicate the relative amounts of the reactants and products
spectator ion
an ion that appears on both sides of an equation and is not directly involved in the reaction
