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. The general formula is: A + BC → AC + B.

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. The general formula is: AB + CD → CB + AD.

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. The general formula is: Hydrocarbon + O₂ → CO₂ + H₂O.
