Types of Reactions

Synthesis A + B  AB Two substances COMBINE to form one.

Decomposition AB  A + B One substance separates to form 2 or more substances Electrolysis Heat

Single Displacement A + BC  AC + B One element and a compound form a new compound and a different element

Reactivity Series More reactive element will form a compound in the products More reactive = towards top of list

Double Displacement AB + CD  AD + CB Two compounds rearrange to form two new compounds Each compound “switches partners”

Combustion CH4 + O2  CO2 + H2O - A compound containing CARBON reacts with oxygen to form carbon dioxide and water.
