Front

Define Synthesis Reaction.

Back

A type of chemical reaction where two or more reactants combine to form a single product.

Front

Define Decomposition Reaction.

Back

A type of chemical reaction where a single compound breaks down into two or more simpler products.

Front

Define Single Replacement Reaction.

Back

A type of chemical reaction where one element replaces another element in a compound.

Front

Define Double Replacement Reaction.

Back

A type of chemical reaction where two compounds exchange ions or bonds to form two new compounds.

Front

Define Combustion Reaction.

Back

A type of chemical reaction that occurs when a substance combines with oxygen, releasing energy in the form of light and heat.

Front

Example of a Synthesis Reaction.

Back

2H₂ + O₂ → 2H₂O (Hydrogen gas combines with oxygen gas to form water.)

Front

Example of a Decomposition Reaction.

Back

2H₂O → 2H₂ + O₂ (Water decomposes into hydrogen and oxygen gases.)

Front

Example of a Single Replacement Reaction.

Back

Zn + CuSO₄ → ZnSO₄ + Cu (Zinc replaces copper in copper sulfate.)
