Types of Chemical Reactions

Front

What is a Decomposition Reaction?

Back

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

Front

What is a Composition/Synthesis Reaction?

Back

A type of chemical reaction where two or more substances combine to form a single compound. Example: A + B → AB.

Front

What is a Single Replacement Reaction?

Back

A type of chemical reaction where an element replaces another element in a compound. Example: A + BC → B + AC.

Front

What is a Double Replacement Reaction?

Back

A type of chemical reaction where two compounds exchange ions or bonds to form two new compounds. Example: AB + CD → AD + CB.

Front

What is a Combustion Reaction?

Back

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 does the Law of Conservation of Mass state?

Back

In a chemical reaction, the total mass of the reactants must equal the total mass of the products.

Front

What is the general form of a Decomposition Reaction?

Back

AB → A + B, where AB is the compound that breaks down.

Front

What is the general form of a Composition/Synthesis Reaction?

Back

A + B → AB, where A and B are the reactants that combine.

Front

What is the general form of a Single Replacement Reaction?

Back

A + BC → B + AC, 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.
