Question

A)

Answer 1

A  formula unit of the nitrate salt of Q is Q(NO3)2.

What is IUPAC nomenclature?

The IUPAC nomenclature was put together by the international Union of Pure and applied chemistry in order to have a uniform way of naming compounds.

We shall now find the names of the compounds;

1) Na* and HPO4²- ; sodium hydrogen tetraoxophoshate V

2) Potassium cation and cyanide anion ; Potassium cyanide

3) Calcium cation and hypochlorite anion; Calcium oxochlorate I

Knowing that the  valency of NO3^- is one and that the compound formed between Q and  CO3²- has the formula QCO3 we can conclude that a formula unit of its nitrate salt is Q(NO3)2.
