Balancing Chemical Reactions and Types

Front

What is a decomposition reaction?

Back

A decomposition reaction is a type of chemical reaction where one compound breaks down into two or more simpler substances. General formula: AB → A + B.

Front

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. General formula: A + B → AB.

Front

What is a single replacement reaction?

Back

A single replacement reaction is a type of chemical reaction where one element replaces another element in a compound. General formula: AB + C → AC + B.

Front

What is a double replacement reaction?

Back

A double replacement reaction is a type of chemical reaction where the anions and cations of two different compounds exchange places to form two new compounds. General formula: AB + CD → AC + BD.
