chemical reaction
A change in which one or more substances are converted into a new substance is called a
double-displacement reaction
If a precipitate, water, or a gas forms when two ionic compounds in solution are combined, the reaction is
inhibitor
A substance that prevents certain chemical reactions is a
synthesis reaction
when two or more substances combine in a chemical reaction to form another substance
A+B=>AB
decomposition reaction
The breakdown of a substance into two or more simpler substances is a
AB=>A+B
reactants
In a chemical equation, the substances that react are called
catalyst
A substance that speeds up a chemical reaction without itself being permanently changed is a
endothermic reaction
A reaction the requires energy in the form of heat is a
single-displacement reaction
When one element replaces another in a compound
A+BC=>AC+B
exothermic reaction
If the energy released in a chemical reaction is primarily in the form of heat, that reaction is a
coefficients
Numbers in front of the symbols and formulas in an equation that represent the number of units of each substances taking part in a reactio is called
balanced
If the number of atoms of each element on the left side of an equation is equal to the number of atoms of each element on the right side of the equation, the equation is
products
In a chemical equation the substances that are produced are called
precipitate
An insoluble solid that forms when two ionic compounds in solution are combined is a
AB+CD=>AD+CB
(s)
solid
(l)
liquid
(aq)
aqueous solution
(g)
gas
combustion reaction
This reaction occurs when a substance reacts with oxygen to produce energy in the form of heat and light
active series
A metal will replace any other metal that is less active
Law of Conservation of Mass
The mass of the products always equals the mass of the reactants
chemical equation
a way to describe a chemical reaction using chemical formulas and other symbols
