Types of Chemical Reactions
Maggie Lou Geiger
Synthesis
-Definition: A reaction in which two or more substances react to form a single substance.
-Equation: A+B=AB
-Examples: H2+O2--->H2O
Decomposition
-Definition: A reaction in which a compound breaks down into two or more simpler substances.
-Equation: AB--->A+B
-Examples: NaCl--->Na+Cl2
Single Replacement
-Definition: A reaction in which one element takes the place of another element in a compound.
-Equation: A+BC--->B+AC
-Examples: F2+MgBr2--->Br2+MgF2
Double Replacement
-Definition: One in which two different compounds exchange positive ions and form two new compounds.
-Equation: AB+CD--->AD+BC
-Examples: NaBr+H2SO4--->HBr+Na2SO4
Combustion
-Definition: One in which a substance reacts rapidly with oxygen, often producing heat and light.
-Equation: None
-Examples: CxHx+O2--->CO2+H2O
