Answer 2

A chemical formula identifies each constituent element by its chemical symbol and indicates the proportionate number of atoms of each element.

RULES FOR WRITING CHEMICAL FORMULA

• Write down the symbols of the elements / ions, which combine to form a molecule of the compound, side by side.

• Write the valency of each element / ion.

Interchange the valencies of the elements / ions and write as the subscript.

• The radical / polyatomic ions must be written in brackets, before the subscript is written.

Hope it helps :D
