Table 2. Classification of Chemical Reactions
Type of Reaction
General Description and Example(s)
Combination
Two reactants combine to form a single product. The reactants may be elements or
compounds. Also calied a synthesis reaction.
Zn(s) + L(s) → Znl,(s)
CaO(s) + H,O(1) → Ca(OH),(s)
Decomposition
One reactant, a compound, breaks down to give two or more products.
2H,0,(aq) → 2H,0(1) + 0,(g)
Single
Replacement
An element reacts with a compound and replaces one of the elements in the compound.
Metals replace hydrogen or other metals; nonmetals replace nonmetals.
Zn(s) + 2HCI(aq) → H,(g) + ZNCI,(ag)
Cu(s) + 2A£NO3(aq) → 2Ag(s) + Cu(NO,),(aq)
Cl,(aq) + 2Nal(aq)
L(aq} + 2NaCl(aq)
Double
Two ionic compounds (or compounds that break apart to form ions in solution)
exchange ions to form new compounds. Examples include precipitation reactions
(driving force is formation of a precipitate), acid–base reactions (driving force is
formation of water), and gas-forming reactions (driving force is evolution of a gas).
NaCl(aq) + A£NO3(aq)
H,SO,(aq) + 2NaOH(aq) → Na,SO̟(aq) + 2H,0(1)
Na,SO,(aq) + 2HCI(aq)
Replacement
A£CI(s) + NaNO3(aq)
2NAÇI(aq) + H,0(1) + SO,(g)
Combustion
A compound burns in the presence of oxygen, producing energy in the form of heat and
light. The combustion of organic compounds produces carbon dioxide and water.
C,H;(1) + 60,(g) → 4CO,(g) + 4H,0(g)
