Chemical Reaction Types

Front

What is a decomposition reaction?

Back

A chemical reaction where one reactant breaks down into two or more products. Example: AB → A + B.

Front

What type of reaction occurs when two substances react to form a single product?

Back

Synthesis reaction. Example: A + B → AB.

Front

What is a single replacement reaction?

Back

A reaction where an element reacts with a compound and takes the place of another element in that compound. Example: Zn + 2HCl → ZnCl2 + H2.

Front

What is a double replacement reaction?

Back

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

Front

How do you balance a chemical equation?

Back

By ensuring the number of atoms for each element is the same on both sides of the equation.

What is the general form of a synthesis reaction?

Back

A + B → AB.

Front

What is combustion reaction?

Back

A reaction where a substance combines with oxygen, releasing energy in the form of light or heat. Example: CH4 + 2O2 → CO2 + 2H2O.
