Types of Chemical Reactions

Front

What is a Single Replacement Reaction?

Back

A chemical reaction where one element replaces another in a compound, represented by the general formula: A + CD → C + AD.

Front

What is a Synthesis Reaction?

Back

A type of chemical reaction where two or more simple substances combine to form a more complex product, represented by the general formula: A + B → AB.

Front

What is a Decomposition Reaction?

Back

A reaction in which a single compound breaks down into two or more simpler products, represented by the general formula: AB → A + B.

Front

What is a Combustion Reaction?

Back

A chemical reaction that occurs when a substance combines with oxygen, releasing energy in the form of light or heat, typically represented as: C_xH_y + O_2 → CO_2 + H_2O.

Front

What is a Double Replacement Reaction?

Back

A reaction where two compounds exchange ions or bonds to form two new compounds, represented by the general formula: AB + CD → AD + CB.
