Types of Chemical Reactions

Front

What is a Synthesis (Combination) Reaction?

Back

A reaction where two or more reactants combine to form a single product. Example: A + B → AB.

Front

What is a Decomposition Reaction?

Back

A reaction where a single compound breaks down into two or more simpler products. Example: AB → A + B.

Front

What is a Single Replacement Reaction?

Back

A reaction where one element replaces another in a compound. Example: A + BC → AC + B.

Front

What is a Double Replacement Reaction?

Back

A reaction where the anions and cations of two different compounds switch places, forming two new compounds. Example: AB + CD → AD + CB.

Front

What is a Combustion Reaction?

Back

A reaction that involves the burning of a substance in the presence of oxygen, producing energy, carbon dioxide, and water. Example: CxHy + O2 → CO2 + H2O.
