Types of reactions

Front

What is a Decomposition Reaction?

Back

A chemical reaction where one compound breaks down into two or more simpler products. Example: Al(OH)₃ → Al₂O₃ + H₂O.

What is a Synthesis Reaction?

Back

A chemical reaction where two or more reactants combine to form a single product. Example: 4Si + S₈ → 2Si₂S₄.

Front

What is a Single Displacement Reaction?

Back

A chemical reaction where one element replaces another in a compound. Example: 3Ca + 2AlCl₃ → 3CaCl₂ + 2Al.

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: C₄H₁₂ + O₂ → CO₂ + H₂O.

What is the general form of a Single Displacement Reaction?

Back

A + BC → AC + B, where element A displaces element B in compound BC.

Front

What is the general form of a Double Displacement Reaction?

Back

AB + CD → AD + CB, where the anions and cations of two different compounds exchange places.

Front

What is an example of a Decomposition Reaction?

Back

2H₂O → 2H₂ + O₂, where water decomposes into hydrogen and oxygen.
