Identifying Types of Reactions

Front

What is a Synthesis Reaction?

Back

A synthesis reaction is a type of chemical reaction where two or more simple substances combine to form a more complex product. Example: 2H₂ + O₂ → 2H₂O.

What is a Decomposition Reaction?

Back

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

Front

What is a Single Replacement Reaction?

Back

A single replacement reaction is a type of chemical reaction where one element replaces another in a compound. Example: Zn + CuSO₄ → ZnSO₄ + Cu.

Front

What is a Combustion Reaction?

Back

A combustion reaction is a type of chemical reaction that occurs when a substance combines with oxygen, releasing energy in the form of light or heat. 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 a single product AB.

Front

What is the general form of a Decomposition Reaction?

Back

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

Front

What is the general form of a Single Replacement Reaction?

Back

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

Front

What is the general form of a Combustion Reaction?

Back

Hydrocarbon + O₂ → CO₂ + H₂O, where a hydrocarbon reacts with oxygen to produce carbon dioxide and water.
