Chemical Reaction Types

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.

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 substances. 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: Fe + CuSO₄ → FeSO₄ + 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 the general form of a synthesis reaction?

Back

The general form of a synthesis reaction is A + B → AB, where A and B are reactants that combine to form product AB.

Front

What is the general form of a decomposition reaction?

Back

The general form of a decomposition reaction is AB → A + B, where compound AB breaks down into its components A and B.

Front

What is the general form of a single replacement reaction?

Back

The general form of a single replacement reaction is A + BC → AC + B, where element A replaces element B in compound BC.

Front

What is the general form of a double replacement reaction?

Back

The general form of a double replacement reaction is AB + CD → AD + CB, where the ions of two compounds exchange places.
