Many chemical compounds are present in egg shell. As such it can not be represented as a simple chemical formula.

Explanation:

The ingredient chemicals in eggshells are:

  1. Calcium Carbonate. The shell is about #95%# #"CaCO"_3#.
  2. Calcium Phosphate. #"Ca"_3("PO"_4)_2#
  3. Magnesium Carbonate. #"MgCO"_3#
    The constituents 2 and 3 make the remaining #5%.#
  4. Some soluble and insoluble proteins are also present in traces.

Crushing of an egg shell will not change its chemical composition.
