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 Combustion Reaction?

Back

A reaction that involves a hydrocarbon reacting with oxygen to produce carbon dioxide and water. Example: C4H12 + 7O2 → 4CO2 + 6H2O.

Front

What is a Single Replacement Reaction?

Back

A reaction where one element replaces another in a compound. Example: 2Na + 2H2O → 2NaOH + H2.

Front

What is a Synthesis Reaction?

Back

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

Front

What are the products of a Combustion Reaction?

Back

Carbon dioxide (CO2) and water (H2O).

Front

What is the general form of a Decomposition Reaction?

Back

AB → A + B, where AB is a compound that breaks down into its components.

Front

What is the general form of a Synthesis Reaction?

Back

A + B → AB, where two or more reactants combine to form a compound.

Front

What is the general form of a Single Replacement Reaction?

Back

A + BC → AC + B, where an element replaces another in a compound.

Front

What is the general form of a Double Replacement Reaction?

Back

AB + CD → AD + CB, where the anions and cations of two different compounds exchange places.

Front

What is an example of a Double Replacement Reaction?

Back

AgNO3 + NaCl → AgCl + NaNO3.
