Types of Reactions

Front

What is a Synthesis Reaction?

Back

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

Front

What is a Decomposition Reaction?

Back

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

Front

What is a Single Replacement Reaction?

Back

A reaction where one element replaces another element in a compound.

Front

What is a Double Replacement Reaction?

Back

A reaction where two compounds exchange ions to form two new compounds.

Front

What is a Combustion Reaction?

Back

A reaction that involves a hydrocarbon reacting with oxygen to produce carbon dioxide and water.

Example of a Synthesis Reaction.

Back

2H₂ + O₂ → 2H₂O (Hydrogen and oxygen combine to form water.)

Front

Example of a Decomposition Reaction.

Back

2H₂O → 2H₂ + O₂ (Water breaks down into hydrogen and oxygen.)

Front

Example of a Single Replacement Reaction.

Back

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