Types of Reactions

Front

What is a Synthesis Reaction?

Back

A reaction where two or more reactants combine to form a single product. Example: 2H₂ + O₂ → 2H₂O.

Front

What is a Decomposition Reaction?

Back

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

Front

What is a Combustion Reaction?

Back

A reaction that involves a hydrocarbon reacting with oxygen to produce carbon dioxide and water. Example: CH₄ + 2O₂ → CO₂ + 2H₂O.

Front

What is a Single Replacement Reaction?

Back

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

Front

What is a Double Replacement Reaction?

Back

A reaction where two compounds exchange ions to form two new compounds. Example: Na₂S + 2HCl → 2NaCl + H₂S.

Front

What are the products of a Combustion Reaction?

Back

Carbon dioxide (CO₂) and water (H₂O).

Front

What is the general form of a Synthesis Reaction?

Back

A + B → AB, where A and B are reactants and AB is the product.

Front

What is the general form of a Decomposition Reaction?

Back

AB → A + B, where AB is the reactant that breaks down into A and B.

Front

What is the general form of a Single Replacement Reaction?

Back

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

Front

What is the general form of a Double Replacement Reaction?

Back

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