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 reactants combine to form a single product. Example: 2 NH₃ + H₂SO₄ → (NH₄)₂SO₄.

What is a double displacement reaction?

Back

A double displacement reaction is a type of chemical reaction where two compounds exchange ions to form two new compounds. Example: Na₃PO₄ + 3 KOH → 3 NaOH + K₃PO₄.

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: Cu + 2 AgNO₃ → Cu(NO₃)₂ + 2 Ag.

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.

What is the general form of a synthesis reaction?

Back

A + B → AB, where A and B are reactants that combine to form product AB.
