A formula unit of the nitrate salt of Q is Q(NO3)2.
<h3>What is IUPAC nomenclature?</h3>
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.

C is the answer for increasing Atomic number
Answer:
Partial pressure of Ne = 366 mmHg
Explanation:
In a mixture, the sum of partial pressures for each gas, is the total pressure for the system.
Partial pressure He: 43 mmHg
Partial pressure Ar: 835 mmHg
Partial pressure Xe: 111 mmHg
Partial pressure Ne: ?
Total pressure = 1355 mmHg
43 + 835 + 111 + x = 1355
989 + x = 1355
x = 1355 - 989 → 366
It is true, here is evidence to this question "<u>People are heterotrophs</u>: we eat plants or meat to stay alive. You might say, well, isn't everything a heterotroph? A lot of creatures are, including giraffes, dogs, fish, <em>horses </em>" I hope this helps you with what your doing.
