Chemical Reaction Types

Front

What is a Decomposition Reaction?

Back

A chemical reaction where one compound breaks down into two or more simpler substances. Example: Ni(ClO3)2 → NiCl2 + O2.

Front

What is a Synthesis Reaction?

Back

A chemical reaction where two or more substances combine to form a single compound. Example: A + B → AB.

Front

What is a Single Replacement Reaction?

Back

A chemical reaction where one element replaces another in a compound. Example: A + BC → B + AC.

Front

What is a Double Replacement Reaction?

Back

A chemical reaction where the anions and cations of two different compounds switch places, forming two new compounds. Example: AB + CD → CB + AD.
