Types of Reactions

Front

What is a Decomposition Reaction?

Back

A reaction where a single compound breaks down into two or more simpler products. Example: 2Pb(NO3)2 → 2PbO + 4NO2 + O2.

Front

What is a Synthesis Reaction?

Back

A reaction where two or more reactants combine to form a single product. Example: P4 + 3O2 → 2P2O3.

Front

What is a Double Displacement Reaction?

Back

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

Front

What is a Single Displacement Reaction?

Back

A reaction where one element replaces another in a compound. Example: Zn + CuSO4 → ZnSO4 + Cu.

Front

What are the characteristics of a Combustion Reaction?

Back

A reaction that involves the burning of a substance in the presence of oxygen, producing heat and light. Example: CH4 + 2O2 → CO2 + 2H2O.

Front

What is the general form of a Synthesis Reaction?

Back

A + B → AB, where A and B are reactants that combine to form product AB.

Front

What is the general form of a Decomposition Reaction?

Back

AB → A + B, where compound AB breaks down into its components A and B.

Front

What is the general form of a Double Displacement Reaction?

Back

AB + CD → AD + CB, where the ions of two compounds exchange places.

Front

What is the general form of a Single Displacement Reaction?

Back

A + BC → AC + B, where element A displaces element B in compound BC.

Front

What is an example of a Combustion Reaction?

Back

C3H8 + 5O2 → 3CO2 + 4H2O, where propane combusts in oxygen.
