A combustion reaction occurs when oxygen combines with another compound to form water and carbon dioxide. These reaction are exothermic, meaning they produce heat.

Describe a combustion reaction.

A decomposition reaction occurs when a complex molecule breaks down to its elements or simpler compounds.

Describe a decomposition reaction.

A double displacement reaction occurs when the anions and cations of two different molecules switch places, forming two entirely different compounds.

Describe a double displacement reaction.

A single displacement reaction occurs when one more reactive element trades places with another element in a compound.

Describe a single displacement reaction.

A synthesis reaction occurs when two or more elements or simple compounds combine to form a more complicated substance.

Describe a synthesis reaction.

A substance that forms in a chemical reaction

Product

A substance or molecule that participates in a chemical reaction
