Classifying Chemical Equations

Front

What is a Decomposition Reaction?

Back

A chemical reaction where a single compound breaks down into two or more simpler products. Example: 2HgClO3 → 2HgO + Cl2.

Front

What is a Double Replacement Reaction?

Back

A chemical reaction where two compounds exchange ions or bonds to form two new compounds. Example: AB + CD → AD + CB.

Front

What is a Single Replacement Reaction?

Back

A chemical reaction where one element replaces another in a compound. Example: Cl2 + 2KI → I2 + 2KCl.

Front

What is a Synthesis Reaction?

Back

A chemical reaction where two or more simple substances combine to form a more complex product. Example: 2 C5H5 + Fe → Fe(C5H5)2.

Front

What is a Combustion Reaction?

Back

A chemical reaction that occurs when a substance combines with oxygen, releasing energy in the form of light or heat. Example: 2C5H10 + 15O2 → 10CO2 + 10H2O.

Synthesis Reaction.

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 compound breaks down into its components.
