5 COMMON TYPES OF CHEMICAL REACTIONS
FORMATION REACTIONS |
|
Definition
* A chemical reaction in which 2 elements combine to form a compound
* The general form of a formation reaction is
A+B =) AB
(A + B represent different elements, AB represents the compound form)
(Chemists use the upper case letters A, B, C, & D to represent elements in the 5 common types of reactions)

DECOMPOSITION REACTION |
|
Definition
* A chemical reaction in which a compound is broken up into its elements
* The general form of a decomposition reaction is
AB =) A + B
(AB represents a compound; A & B represent different elements) |

HYDROCARBON COMBUSTION REACTION |
|
Definition
* A chemical reaction in which a hydrocarbon reacts with oxygen to form carbon dioxide and water
* The general form of a hydrocarbon combustion reaction is
CxHy + O2(g) =) CO2(G) +H2O(g)
(x & y represent the number of carbon and hydrogen atoms in the hydrocarbon) |

5 COMMON TYPES OF CHEMICAL REACTIONS
SINGLE REPLACEMENT REACTION |
|
Definition
* A chemical reaction in which a compound reacts with an element to form a new compound
* The general form of a single replacement reaction is
A + BC =) B + AC
(A is 1 metal element, B is another metal element and C is a non-metal element) |
|

Term
5 COMMON TYPES OF CHEMICAL REACTIONS
Not all single replacement reactions involve the replacement of a metal ion by a metal element. In some single replacement reactions, the non-metal ion is replaced by the non-metal element.
(The non-metal ions trade places)
|
|
Definition
The general form in this case is
D + BC =) C + BD
(In this formula, D & C are 2 non-metals
& B is a metal) |

5 COMMON TYPES OF CHEMICAL REACTIONS
DOUBLE REPLACEMENT REACTION |
|
Definition
* A chemical reaction in which 2 compounds react to form 2 new compounds
* The general form of a double replacement reaction is
AB + CD =) AD + CB
(In this formula, A and C are positive ions and B and D are negative ions) |
