Types of Reactions
Synthesis: when 2 or more simple compounds combine to form a more complicated one
Decomposition: when a complex molecule breaks down to make simpler ones
Single-replacement: when 1 element trade places with another element in a compound
Double Replacement:when the anions and cations of two different molecules switch places, forming two entirely different compounds
Combustion: when oxygen combines with another compound to form water and carbon dioxide, these reactions are exothermic
