Types of Reactions

Front

What is a Decomposition Reaction?

Back

A chemical reaction where a single compound breaks down into two or more simpler products. Example: 2Pb(NO3)2 → 2PbO + 4NO2 + 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.

Front

What is a Single Replacement Reaction?

Back

A chemical reaction where one element replaces another in a compound. Example: Fe + H2SO4 → Fe2(SO4)3 + H2.

Front

What is a Double Replacement Reaction?

Back

A chemical reaction where two compounds exchange ions or bonds to form two new compounds. Example: PbCl2 + AgNO3 → Pb(NO3)2 + AgCl.

Front

What is a Combustion Reaction?

Back

A chemical reaction that occurs when a substance combines with oxygen, releasing energy in the form of light or heat. Example: CH4 + 2O2 → CO2 + 2H2O.
