I believe the correct answer would be reactants. When heat is added to the reaction mixture, the formation of reactants would be favored since the reaction is an exothermic reaction. Hope this answers the question. Have a nice day.

Boyle’s law gives the relationship between pressure and volume of gases. It states that at constant temperature the pressure of gas is inversely proportional to volume of gas.
PV = k
Where P is pressure V is volume and k is constant
P1V1 = P2V2
Parameters at STP are on the left side and parameters for the second instance are on the right side of the equation
P1 - standard pressure - 1.0 atm
Substituting the values in the equation
1.0 atm x 5.00 L = P x 15.0 L
P = 0.33 atm
New pressure is 0.33 atm

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.
