Types of ReactionsTypes of Reactions

Single DisplacementSingle Displacement Double DisplacementDouble Displacement CombinationCombination CombustionCombustion DecompositionDecomposition

Single DisplacementSingle Displacement

A chemical reaction whereby a free element A chemical reaction whereby a free element substitutes for another element in a compound.substitutes for another element in a compound.

In this type of reaction, displacement normally In this type of reaction, displacement normally occurs when A is more reactive than Boccurs when A is more reactive than B

Generic Formula:Generic Formula: A + BX AX + BA + BX AX + B A + BX B + AXA + BX B + AX A + BX X + AB (or BA)A + BX X + AB (or BA)


Examples:Examples: Mg + 2HCl MgClMg + 2HCl MgCl22 + H + H22

Cu + AgNOCu + AgNO3 3 Ag + CuNOAg + CuNO33

ClCl2 2 + CH+ CH4 4 4H + CCl4H + CCl22

Double DisplacementDouble Displacement

When two or more reactants form one When two or more reactants form one product which is either a solid compound or product which is either a solid compound or a molecular compounda molecular compound

Generic Formula:Generic Formula: AX + BY AY + BXAX + BY AY + BX


Examples:Examples:

Ag NOAg NO33 + NaCl AgCl + NaNO + NaCl AgCl + NaNO33

Pb(NOPb(NO33))22 + 2 KI PbI + 2 KI PbI22 + 2 KNO + 2 KNO33

CombinationCombination

A chemical reaction where one compound is A chemical reaction where one compound is formed from two elements and/or formed from two elements and/or compoundscompounds

Generic Formula:Generic Formula: A + B ABA + B AB


Examples:Examples: 8 Fe + S8 Fe + S88 8 FeS 8 FeS

CaO + COCaO + CO22 CaCO CaCO33

DecompositionDecomposition

A chemical reaction where one compound A chemical reaction where one compound decomposes into two or more elements decomposes into two or more elements and/or compoundsand/or compounds

Generic Formula:Generic Formula: AB A + BAB A + B

DecompositionDecomposition

Examples:Examples:

2H2H22O OO O22 + 2H + 2H22OO

HH22COCO33 H H22O + C0O + C022

CombustionCombustion

A chemical reaction of an element or A chemical reaction of an element or compound with oxygencompound with oxygen

Combustion normally is with a flameCombustion normally is with a flame

Generic Formula:Generic Formula: Carbon-Hydrogen Compound Carbon Dioxide + WaterCarbon-Hydrogen Compound Carbon Dioxide + Water


When carbon-hydrogen compounds go When carbon-hydrogen compounds go through combustion with an excess of through combustion with an excess of oxygen, the products are carbon dioxide and oxygen, the products are carbon dioxide and waterwater

When these compounds go through When these compounds go through combustion with less oxygen, the products combustion with less oxygen, the products can also be carbon monoxidecan also be carbon monoxide


Example:Example:

With an excess of oxygen…With an excess of oxygen…

CHCH44 + 2O + 2O22 CO CO22 + 2H + 2H22OO


Example:Example:

With less oxygen needed…With less oxygen needed…

2C2C88HH1818 + 17O + 17O22 16CO + 18H 16CO + 18H22OO
