What is a Single Replacement Reaction?

Back

A chemical reaction where one element replaces another in a compound. Example: Cl2 + 2NaBr → 2NaCl + Br2.

What is a Double Replacement Reaction?

Back

A chemical reaction where two compounds exchange ions or bonds to form two new compounds. Example: CuCl2 + Na2SO4 → NaCl + CuSO4.

What is a Decomposition Reaction?

Back

A chemical reaction where a single compound breaks down into two or more simpler substances. Example: KClO3 → KCl + O2.

Front

What is a Synthesis Reaction?

Back

A chemical reaction where two or more simple substances combine to form a more complex product. Example: A + B → AB.

What is the Law of Conservation of Mass?

Back

In a chemical reaction, mass is neither created nor destroyed; it remains constant.

What is a Reactant?

Back

A substance that undergoes change during a chemical reaction.
