Decomposition Reactions
Essentially, decomposition reaction are the opposite of combination
reactions. A compound decomposes (i.e.,"splits­up") into two or more
compounds and/or elements. For example mercury(II) oxide will,
upon heating, decompose into mercury metal and oxygen:

Since heat had to be added to make this reaction go, it is an
endothermic reaction. Most decomposition reactions are endothermic.
Another example of a decomposition reaction is the heating of
calcium carbonate (sea shells, chalk):
