Types of Reactions

Front

What is a decomposition reaction?

Back

A decomposition reaction is a type of chemical reaction where one compound breaks down into two or more simpler products. General formula: AB → A + B.

What is the general formula for a double displacement reaction?

Back

The general formula for a double displacement reaction is AB + CD → AC + BD, where two compounds exchange ions.

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. General formula: A + B → AB.

Front

What is a combustion reaction?

Back

A combustion reaction is a chemical reaction that occurs when a substance reacts with oxygen, producing energy in the form of heat and light. Example: C4H12 + O2 → CO2 + H2O.

Front

What is a single replacement reaction?

Back

A single replacement reaction is a type of chemical reaction where one element replaces another in a compound. General formula: A + BC → AC + B.

Front

What is a double replacement reaction?

Back

A double replacement reaction is a type of chemical reaction where two compounds exchange ions to form two new compounds. Example: 3KOH + H3PO4 → K3PO4 + 3H2O.
