Classifying Chemical Reactions

Front

What is a synthesis reaction?

Back

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

Front

What is a decomposition reaction?

Back

A decomposition reaction is a type of chemical reaction where a single compound breaks down into two or more simpler products. Example: 2H₂O → 2H₂ + O₂.

Front

What is a single replacement reaction?

Back

A single replacement reaction is a type of chemical reaction where one element replaces another in a compound. General formula: A + BC → B + AC. Example: Zn + CuSO₄ → ZnSO₄ + Cu.

Front

What is a double replacement reaction?

Back

A double replacement reaction is a type of chemical reaction where two compounds exchange ions or bonds to form two new compounds. General formula: AB + CD → AD + CB. Example: Na₂S + 2HCl → 2NaCl + H₂S.

Front

What is combustion reaction?

Back

A combustion reaction is 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 is the general formula for a synthesis reaction?

Back

The general formula for a synthesis reaction is A + B → AB.

Front

What is the general formula for a decomposition reaction?

Back

The general formula for a decomposition reaction is AB → A + B.

Front

What is the general formula for a single replacement reaction?

Back

The general formula for a single replacement reaction is A + BC → B + AC.

Front

What is the general formula for a double replacement reaction?

Back

The general formula for a double replacement reaction is AB + CD → AD + CB.

Front

What is the difference between synthesis and decomposition reactions?

Back

Synthesis reactions combine multiple reactants to form one product, while decomposition reactions break down one compound into multiple products.
