Types of Reactions

Front

What is a Single Displacement Reaction?

Back

A reaction where one element replaces another in a compound, represented as A + BC → AC + B.

Front

Example of a Single Displacement Reaction?

Back

3Ca + 2AlCl₃ → 3CaCl₂ + 2Al.

Front

What is a Synthesis Reaction?

Back

A reaction where two or more reactants combine to form a single product, represented as A + B → AB.

Front

Example of a Synthesis Reaction?

Back

4Si + S₈ → 2Si₂S₄.

Front

What is a Double Displacement Reaction?

Back

A reaction where ions in two compounds exchange places, represented as AB + CD → AD + CB.

Front

Example of a Double Displacement Reaction?

Back

Na₂S + BaCl₂ → BaS + 2NaCl.

Front

What is a Decomposition Reaction?

Back

A reaction where a single compound breaks down into two or more simpler products, represented as AB → A + B.

Front

Example of a Decomposition Reaction?

Back

2H₂O → 2H₂ + O₂.

Front

What is a Combustion Reaction?

Back

A reaction where a substance combines with oxygen, releasing energy in the form of light or heat, typically producing CO₂ and H₂O.

Front

Example of a Combustion Reaction?

Back

CH₄ + 2O₂ → CO₂ + 2H₂O.
