Answers Answers

Answer 2

The chemical formula for compound zinc (II) phosphate is Zn₃(PO₄)₂.

Zinc (II) phosphate is an inorganic chemical compound that is made up of zinc cations and phosphate anions .The chemical formula for zinc (II) phosphate is obtained by combining three zinc cations with two phosphate anions to achieve the neutral charge.

Chemical formula is a way of representing the number of atoms present in a compound or molecule.It is written with the help of symbols of elements. It also makes use of brackets and subscripts.

Subscripts are used to denote number of atoms of each element and brackets indicate presence of group of atoms. Chemical formula does not contain words. Chemical formula in the simplest form is called empirical formula.

It is not the same as structural formula and does not have any information regarding structure.It does not provide any information regarding structure of molecule as obtained in structural formula.

Thus, chemical formula for compound zinc (II) phosphate is Zn₃(PO₄)₂.
