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: 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
CombustionCombustion
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
CombustionCombustion
Example:Example:
With an excess of oxygen…With an excess of oxygen…
CHCH44 + 2O + 2O22 CO CO22 + 2H + 2H22OO
CombustionCombustion
Example:Example:
With less oxygen needed…With less oxygen needed…
2C2C88HH1818 + 17O + 17O22 16CO + 18H 16CO + 18H22OO
