5 types of reactions
- Synthesis-- 2 elements combine to form a compound
- Decomposition--A compound breaks down into elements and/or smaller compounds
- Single Replacement--an element and compound react to form a different element and compound
- Douple Replacement-- Two elements in two compounds switch spots ( usually non-metal elements switch )
- Combustion-

Synthesis
Decomposition
Single Replacement: You must use activity series for these
Double Replacement: AB + CD ---> AD + CB
Combustion Reaction
Neutralization reaction: A reaction between an acid and a base
- Formation of Binary compound: A + B ---> AB
- Metal Oxide and water: MO + H2O ---> Base
- Nonmetal Oxide and water: (NM)O + H2O ---> Acid
Decomposition
- Binary compounds: AB ---> A + B
- Metallic CARBONATES: MCO3 --->MO + CO2
- Mecallic HYDROGEN CARBONATES: Mhco3 ---> MCO3(s) + H2O (L) + Co2 (g)
- Metallic HYDROXIDES: MOH --->MO + H2O
- Metallic CHLORATES: MClO3 ---> MCl + O2
- Oxyacids decompose to non metal oxides and water: acid---> (NM)O +H2O
Single Replacement: You must use activity series for these
- Metal-Metal replacement: A + BC ---> AC + B
- Active metal replaces H from water: M + H2O ---> MOH+H2
- Active metal replaces H from acid: M + HX ---> MX + H2
- Halide-Halide replacement: D + BC ---> BD + C
Double Replacement: AB + CD ---> AD + CB
- Formation of precipitate from solution
- Acid- Base neutralization
Combustion Reaction
- Hydrocarbon + Oxygen---> carbon dioxide + water
- O2 in a reaction by itself lets you know that it is a combustion reaction.
- c = CO2
- H= H2O
- S = SO2
- N = N2
Neutralization reaction: A reaction between an acid and a base
