Identifying Types of 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 combustion reaction?

Back

A combustion reaction is a type of chemical reaction that occurs when a substance reacts with oxygen, producing energy in the form of heat and light. Example: CH₄ + 2O₂ → CO₂ + 2H₂O.

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 + 2HCl → H₂ + ZnCl₂.

Front

What is the general form of a synthesis reaction?

Back

The general form of a synthesis reaction is 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

The general form of a decomposition reaction is AB → A + B, where compound AB breaks down into its components A and B.

Front

What is the general form of a combustion reaction?

Back

The general form of a combustion reaction is Hydrocarbon + O₂ → CO₂ + H₂O, where a hydrocarbon reacts with oxygen to produce carbon dioxide and water.

Front

What is the general form of a single replacement reaction?

Back

The general form of a single replacement reaction is A + BC → AC + B, where element A replaces element B in compound BC.

Front

What are the products of the combustion of propane (C₃H₈)?

Back

The products of the combustion of propane are carbon dioxide (CO₂) and water (H₂O). Example: C₃H₈ + 5O₂ → 3CO₂ + 4H₂O.

Front

What type of reaction is 2Na + Cl₂ → 2NaCl?

Back

This is a synthesis reaction, where sodium (Na) and chlorine (Cl₂) combine to form sodium chloride (NaCl).
