Types of Reactions

Front

What is a Synthesis Reaction?

Back

A synthesis reaction is a type of chemical reaction where two or more simple substances combine to form a more complex product. Example: 2H₂ + O₂ → 2H₂O.

What is a Decomposition Reaction?

Back

A decomposition reaction is a type of chemical reaction where a single compound breaks down into two or more simpler products. Example: 2H₂O → 2H₂ + O₂.

Front

What is a Single Displacement Reaction?

Back

A single displacement reaction is a type of chemical reaction where one element replaces another in a compound. Example: Zn + CuSO₄ → ZnSO₄ + Cu.

Front

What is a Double Displacement Reaction?

Back

A double displacement reaction is a type of chemical reaction where the ions of two compounds exchange places in an aqueous solution to form two new compounds. Example: AgNO₃ + NaCl → AgCl + NaNO₃.

Front

What is a Combustion Reaction?

Back

A combustion reaction is a type of chemical reaction that occurs when a substance combines with oxygen, releasing energy in the form of light or heat. Example: CH₄ + 2O₂ → CO₂ + 2H₂O.

What is the general form of a Synthesis Reaction?

Back

A + B → AB, where A and B are reactants that combine to form a product AB.

Front

What is the general form of a Decomposition Reaction?

Back

AB → A + B, where a compound AB breaks down into its components A and B.

Front

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 ions of two compounds exchange places.

What are the signs of a chemical reaction?

Back

Signs of a chemical reaction include color change, temperature change, gas production, and formation of a precipitate.
