U7: Types of Reactions Practice

Front

What is a Decomposition Reaction?

Back

A reaction where a single compound breaks down into two or more simpler products. Example: Ag2O → Ag + O2.

Front

What is a Single Replacement Reaction?

Back

A reaction where one element replaces another in a compound. Example: Zn + HCl → H2 + ZnCl2.

Front

What is a Double Replacement Reaction?

Back

A reaction where two compounds exchange ions or bonds to form two new compounds. Example: FeBr3 + H2SO4 → HBr + Fe2(SO4)3.

Front

What is a Combustion Reaction?

Back

A reaction that involves the burning of a substance in the presence of oxygen, producing heat and light. Example: C2H2 + O2 → CO2 + H2O.

Front

What is a Synthesis Reaction?

Back

A reaction where two or more reactants combine to form a single product. Example: Fe + Cl2 → FeCl3.

Front

What are the five main types of chemical reactions?

Back

1. Synthesis 2. Decomposition 3. Single Replacement 4. Double Replacement 5. Combustion.

Front

How can you identify a Decomposition Reaction?

Back

Look for a single reactant that breaks down into multiple products.

Front

What is the general form of a Single Replacement Reaction?

Back

A + BC → AC + B, where A replaces B in the compound.

Front

What is the general form of a Double Replacement Reaction?

Back

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

Front

What is the role of oxygen in a Combustion Reaction?

Back

Oxygen acts as a reactant that combines with the fuel to produce energy, carbon dioxide, and water.
