Types of Reactions

What is a Single Displacement Reaction?

• A reaction where two compounds exchange ions.

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

• A reaction that involves the combination of two elements.

• A reaction that produces a gas as a product.

What is a Synthesis Reaction?

• A reaction where two or more simple substances combine to form a more complex product.

• A reaction that breaks down a compound into simpler substances.

• A reaction that involves the exchange of ions between two compounds.

• A reaction that occurs only in the presence of a catalyst.

What is a Decomposition Reaction?

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

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

• A reaction that involves the transfer of electrons between two species.

• A reaction that occurs only in the presence of a catalyst.

What is the general form of a Synthesis Reaction?

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

• A + B → A + B, where A and B remain unchanged.

• A + B → A - B, where A loses B as a product.

• A + B → A × B, where A and B multiply to form a product.

What is the general form of a Decomposition Reaction?

• A + B → AB

• AB → A + B

• A + B + C → AB

• AB + C → A + B

What is an example of a Single Displacement Reaction?

• Fe + CuSO₄ → FeSO₄ + Cu

• 2H₂ + O₂ → 2H₂O

• NaCl + AgNO₃ → AgCl + NaNO₃

• C + O₂ → CO₂

What is a Double Displacement Reaction?

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

• A reaction that involves the breaking of chemical bonds without any exchange of ions.

• A reaction that occurs only in solid-state materials.

• A reaction that produces energy without any reactants.

What is the general form of a Single Displacement Reaction?

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

• A + B → AB, where elements A and B combine to form a compound.

• AB + C → AC + B, where compound AB reacts with element C.

• A + B → A + B, where elements A and B remain unchanged.

What is the general form of a Double Displacement Reaction?

• AB + CD → AD + CB, where the ions of two compounds exchange places.

• AB + CD → AC + BD, where the compounds combine to form a new compound.

• A + B → AB, where two elements combine to form a compound.

• AB + CD → A + B + C + D, where the compounds dissociate into their elements.

What are the signs of a chemical reaction?

• Color change, temperature change, gas production, and formation of a precipitate.

• Only color change and gas production.

• Temperature change and color change only.

• Formation of a precipitate and gas production only.
