5.2 Types of Reactions

Front

What is a Synthesis Reaction?

Back

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

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: BaCl₂ + 2KI → 2KCl + BaI₂.

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 + CD → C + AD. Example: Zn + CuSO₄ → ZnSO₄ + Cu.

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 combines with oxygen, releasing energy in the form of light or heat. Example: CH₄ + 2O₂ → CO₂ + 2H₂O.
