Types of Chemical Reactions

Front

What is a single displacement reaction?

Back

A single displacement reaction is a type of chemical reaction where one element replaces another element in a compound. Example: Cl₂ + 2KI → I₂ + 2KCl.

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: 2 C₅H₅ + Fe → Fe(C₅H₅)₂.

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: Ca(OH)₂ + HNO₃ → Ca(NO₃)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.

What is the general form of a synthesis reaction?

Back

A synthesis reaction can be represented as A + B → AB, where A and B are reactants that combine to form a product AB.

Front

What is the general form of a single displacement reaction?

Back

A single displacement reaction can be represented as A + BC → AC + B, where A displaces B in the compound BC.

Front

What is the general form of a double displacement reaction?

Back

A double displacement reaction can be represented as AB + CD → AD + CB, where the ions of two compounds exchange places.

Front

What is the general form of a decomposition reaction?

Back

A decomposition reaction can be represented as AB → A + B, where a compound AB breaks down into its components A and B.

How do you balance a chemical equation?

Back

To balance a chemical equation, ensure that the number of atoms of each element is the same on both sides of the equation by adjusting coefficients.
