What is a Decomposition Reaction?

Back

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

Front

What is a Single Displacement Reaction?

Back

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

Front

What is a Combination/Synthesis Reaction?

Back

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

Front

What is a Double Displacement Reaction?

Back

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