Types of Chemical Reactions

Front

What is a synthesis (or combination) 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: 2 H₂ + O₂ → 2 H₂O.

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: 2 H₂O → 2 H₂ + 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 + 2 O₂ → CO₂ + 2 H₂O.

Front

What is a single displacement reaction?

Back

A single displacement reaction is a type of chemical reaction where one element displaces another in a compound. Example: Pb + FeSO₄ → PbSO₄ + Fe.

Front

What is a double displacement reaction?

Back

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