Types of Chemical Reactions
By Payton Pierce
Synthesis
- Definition: a reaction in which two or more substances react to form a single substance.
- Equation: A+B --> AB
- Example: H2+O2 --> H2O
Decomposition
- Definition: a reaction in which a compound breaks into two or more simpler substances.
- Equation: AB --> A+B
- Example: 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
- Example: F2+MgBr2 --> Br2+MgF2
Double Replacement
- Definition: two different compounds exchange positive ions and form two new compounds.
- Equation: AB+CD --> AD+BC
- Example: NaBr+H2SO4 --> HBr+Na2SO4
Combustion
- Definition: a substance reacts rapidly with oxygen, often producing hear and light.
- Equation: none
- Example: CxHx+O2 --> CO2+H2O
