on substance breaks down into two or more simpler substances.
Compound=Element+Element

 Single-Displacement; A+BY=AY+B
Occurs when one element replaces another element in a compound
Element+Compound=Compound

 Double-Displacement= AY+BX=BX+BY
Two diffrent atoms in two diffrent compounds exchange places
Compound+Compound=Compound

 Combustion= The products of combustion are always water and carbon dioxide
Hydrocarbon+Oxygen= Water+Carbon Dioxide

Single-Displacement reacts to Zinc it creats bubbles and loud bombing sounds
