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 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 to form two new compounds. Example: AgNO₃ + NaCl → AgCl + NaNO₃.

Front

What is a combustion reaction?

Back

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