Identifying Types of Reactions

Front

What is a combustion reaction?

Back

A combustion reaction is a 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

What is a synthesis reaction?

Back

A synthesis reaction is a type of chemical reaction in which two or more simple substances combine to form a more complex product. Example: 2H₂ + O₂ → 2H₂O.

Front

What is a decomposition reaction?

Back

A decomposition reaction is a 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 + 2HCl → ZnCl₂ + H₂.

Front

What is a double replacement reaction?

Back

A double replacement reaction is a chemical reaction where two compounds exchange ions or bonds to form two new compounds. Example: AgNO₃ + NaCl → AgCl + NaNO₃.

Front

What is the general form of a combustion reaction?

Back

The general form of a combustion reaction is: Hydrocarbon + O₂ → CO₂ + H₂O.

Front

What are the products of a complete combustion reaction?

Back

The products of a complete combustion reaction are carbon dioxide (CO₂) and water (H₂O).

Front

What is the difference between complete and incomplete combustion?

Back

Complete combustion occurs with sufficient oxygen, producing CO₂ and H₂O, while incomplete combustion occurs with limited oxygen, producing CO, soot, or other hydrocarbons.

Front

What is the role of oxygen in combustion reactions?

Back

Oxygen acts as a reactant in combustion reactions, facilitating the reaction with fuel to produce energy, CO₂, and H₂O.

Front

What is an example of a synthesis reaction?

Back

An example of a synthesis reaction is: 2Na + Cl₂ → 2NaCl.
