What is a combustion reaction?

Back

A combustion reaction is a chemical reaction that occurs when a substance (usually a hydrocarbon) reacts with oxygen to produce carbon dioxide and water, releasing energy in the form of heat and light.

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. For example, 2H₂ + O₂ → 2H₂O.

Front

What is a decomposition reaction?

Back

A decomposition reaction is a chemical reaction in which a single compound breaks down into two or more simpler products. For example, 2H₂O₂ → 2H₂O + O₂.

Front

What is a single replacement reaction?

Back

A single replacement reaction is a type of chemical reaction where one element replaces another element in a compound. For example, Zn + CuSO₄ → ZnSO₄ + Cu.

Front

What is a double replacement reaction?

Back

A double replacement reaction is a chemical reaction where the ions of two compounds exchange places in an aqueous solution to form two new compounds. For example, AgNO₃ + NaCl → AgCl + NaNO₃.

What is the general formula for combustion reactions?

Back

Front

What are the products of a complete combustion of hydrocarbons?

Back

The products of a complete combustion of hydrocarbons 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 an example of a synthesis reaction?

Back

An example of a synthesis reaction is: 2H₂ + O₂ → 2H₂O.

Front

What is an example of a decomposition reaction?

Back

An example of a decomposition reaction is: 2H₂O₂ → 2H₂O + O₂.
