Types of Chemical Reactions

Front

What is a Double Replacement Reaction?

Back

A chemical reaction where two compounds exchange ions or bonds to form two new compounds. Example: KOH + H3PO4 → K3PO4 + H2O.

Front

What characterizes a Single Replacement Reaction?

Back

A reaction where one element replaces another in a compound. Example: A + BC → AC + B.

Front

Define Decomposition Reaction.

Back

A reaction where one reactant breaks down into two or more products. Example: 2H2O → 2H2 + O2.

Front

What is a Combustion Reaction?

Back

A reaction that involves oxygen and produces heat and light, typically involving a hydrocarbon. Example: CH4 + 2O2 → CO2 + 2H2O.

Front

What is a Synthesis Reaction?

Back

A reaction where two or more reactants combine to form a single product. Example: A + B → AB.

Front

What are the products of a combustion reaction?

Back

Typically carbon dioxide (CO2) and water (H2O) are produced.

Front

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.

Front

What is the general form of a Decomposition Reaction?

Back

AB → A + B, where a single compound breaks down into two or more products.

Front

What is the role of oxygen in combustion reactions?

Back

Oxygen acts as a reactant that combines with a fuel to produce energy, CO2, and H2O.

Front

What is an example of a Single Replacement Reaction?

Back

Example: Zn + 2HCl → ZnCl2 + H2, where zinc replaces hydrogen in hydrochloric acid.
