Types of chemical reactions

Front

What is a single replacement reaction?

Back

A reaction where one element replaces another in a compound, represented as A + CD → C + AD.

Front

What is a combination reaction?

Back

A reaction where two or more substances combine to form a single product, represented as A + B → AB.

Front

What is a double replacement reaction?

Back

A reaction where the anions and cations of two different compounds switch places, represented as AB + CD → CB + AD.

Front

What is a combustion reaction?

Back

A reaction where a substance combines with oxygen, releasing energy in the form of light or heat, typically represented as C_xH_y + O_2 → CO_2 + H_2O.

Front

What is the general formula for a decomposition reaction?

Back

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

Front

What is the difference between a single replacement and a double replacement reaction?

Back

In a single replacement reaction, one element replaces another in a compound, while in a double replacement reaction, two compounds exchange components.

What is an example of a combustion reaction?

Back

Burning of methane: CH_4 + 2O_2 → CO_2 + 2H_2O.
