LT4.2 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: Na + Br₂ → NaBr.

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. 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. Example: AgF + CaCl₂ → AgCl + CaF₂.

Front

What is a 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 and heat. Example: CH₄ + 2O₂ → CO₂ + 2H₂O.

Front

Identify the products of the reaction: 2C₃H₇(OH) + 9O₂ → ?

Back

The products are 6CO₂ + 8H₂O.

Front

What is the general form of a synthesis reaction?

Back

A + B → AB, where A and B are reactants that combine to form product AB.

Front

What is the general form of a decomposition reaction?

Back

AB → A + B, where compound AB breaks down into its components A and B.

Front

What is the general form of a single replacement reaction?

Back

A + BC → AC + B, where element A replaces B in compound BC.

Front

What is the general form of a double replacement reaction?

Back

AB + CD → AD + CB, where compounds AB and CD exchange components.
