Identifying Types of Chemical Reactions

Front

What is a Synthesis Reaction?

Back

A synthesis reaction is a type of chemical reaction where two or more simple substances combine to form a more complex product. Example: P4 + 3 O2 → 2 P2O3.

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: 2 NO2 → 2 O2 + N2.

Front

What is a Single Replacement Reaction?

Back

A single replacement reaction is a type of chemical reaction where one element replaces another element in a compound. Example: Cu + 2Ag(NO3) → 2Ag + Cu(NO3).

Front

What is a Double Replacement Reaction?

Back

A double replacement reaction is a type of chemical reaction where the anions and cations of two different compounds switch places, forming two new compounds. Example: AB + CD → AD + CB.

What is a 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: CxHy + O2 → H2O + CO2.
