Types of Reactions

Front

What is a synthesis 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 products. Example: AB → A + B.

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: 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 does the law of conservation of mass state?

Back

In a chemical reaction, the mass of the reactants must equal the mass of the products; matter cannot be created or destroyed.

Back

A + B → AB.

Front

What is an example of a decomposition reaction?

Back

2H₂O → 2H₂ + O₂.
