Types of reactions

A chemical reaction where two compounds exchange ions to form two new compounds. Example: PbCl2 + AgNO3 → Pb(NO3)2 + AgCl.

A type of reaction where two or more reactants combine to form a single product. Example: 4Si + S8 → 2Si2S4.

A reaction where one element replaces another in a compound. General formula: A + BC → B + AC. Example: Zn + CuSO4 → ZnSO4 + Cu.

A reaction where a single compound breaks down into two or more simpler products. Example: 2H2O → 2H2 + O2.

AB + CD → CB + AD.

A + B → AB.

A + BC → B + AC.

AB → A + B.

A reaction where a substance combines with oxygen, releasing energy in the form of light or heat. Example: CH4 + 2O2 → CO2 + 2H2O.

Na2SO4 + BaCl2 → BaSO4 + 2NaCl.
