Write the compound with water of cystallisation

Na2C03 10H2O is hydrated sodium carbonate salt or sodium carbonate with water of crystallisation.

Explanation:

                                Na2CO3.10H2O  

Preparation:  

               NaCl +NH3 +H2O+CO2 - >NaHCO3 +NH4Cl  

                     2NaHCO3 - > Na2CO3 + CO2 + H2O  

                      Na2CO3+10H2O - >Na2CO3.10H2O

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.
