A chemical reaction yielding a single product from several reactants. Also called synthesis reaction and combination reaction. composition reaction
A chemical reaction yielding two or more products from a single reactant. decomposition reactions
A chemical reaction in which two ionic compounds swap cations with each other, usually forming a precipitate compound as one of the products. double-replacement reactions
A reaction that must absorb heat from its surroundings to occur. endothermic reactions
A reaction that liberates heat to its surroundings as it occurs. exothermic reactions
The number of electrons that a bonded atom or ion must gain or lose to return to its neutral state. oxidation numbers
A substance (on the right hand side of the equation) that is produced by a chemical reaction. products
A substance (on the left-hand side of the equation) that undergoes a chemical change. reactants
In this reaction, one element in an existing compound is replaced by another element. single-replacement reactions
