Chemical Reaction Types

Front

What is a Synthesis Reaction?

Back

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

Front

What is a Decomposition Reaction?

Back

A decomposition reaction is a type of chemical reaction where a single compound breaks down into two or more simpler products. Example: 2HI → H2 + I2.

Front

What is a Single Replacement Reaction?

Back

A single replacement reaction is a type of chemical 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 double replacement reaction is a type of chemical reaction where two compounds exchange ions or bonds to form two new compounds. Example: AB + CD → AD + CB.

What is Combustion Reaction?

Back

A combustion reaction is a type of chemical reaction that occurs when a substance combines with oxygen, releasing energy in the form of light or heat. Example: CH4 + 2O2 → CO2 + 2H2O.
