The opposite of a synthesis reaction. A complex molecule breaks down to make simpler ones.
When oxygen combines with another compound to form water and carbon dioxide. These reactions are exothermic (they produce heat).
Single Displacement Reaction
When one element trades places with another element in a compound
Double Displacement Reaction
When the anions and cations of two different molecules switch places. They form two entirely different compounds.
involves a transfer of electrons between two species. Any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron.
