types of reactions

Front

What is a single displacement reaction?

Back

A reaction where one element replaces another in a compound, represented by the equation A + BC → AC + B.

Front

What is a double replacement reaction?

Back

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

Front

What is a synthesis reaction?

Back

A reaction where two or more reactants combine to form a single product, represented by the equation A + B → AB.

Front

What is a decomposition reaction?

Back

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

Front

What is a combustion reaction?

Back

A reaction that occurs when a substance combines with oxygen, releasing energy in the form of light or heat, typically producing CO2 and H2O.
